You can configure AS2 connections to specify parameters such as the partner's AS2 ID, encryption and signature algorithms, message compression settings, and MDN (Message Disposition Notification) options. This ensures compliance with AS2 standards and enables encrypted and authenticated message exchange.

HTTP Sender Connection Details: The HTTP Sender adapter in SAP Integration Suite allows you to send HTTP requests to external endpoints or services. You can configure HTTP sender connections to specify details such as the target URL, HTTP method (e.g., POST, GET), request headers, authentication credentials, and payload format. This adapter is commonly used for integrating with RESTful APIs, web services, or HTTP-based endpoints.

Creating Package in Integration Suite(SAP Help Portal - SAP Integration Suite - Package Details): In SAP Integration Suite, a package is a container for organizing and managing artifacts, such as integration flows, APIs, and data mappings. You can create packages to group related artifacts together, making it easier to organize and maintain your integration projects. When creating a package, you can specify metadata such as the package name, description, version, and visibility settings.

Creating Artifact/iFlow in Integration Suite: An artifact, or integration flow (iFlow), is a unit of deployment in SAP Integration Suite that represents a sequence of processing steps for handling messages or data. You can create iFlows within a package to define the flow logic, message transformations, and endpoint configurations required for integrating systems or applications. When creating an iFlow, you can use graphical tools to design the flow logic and configure the various processing steps.

o One branch directly transmits messages to the AS2 receiver.

o The other branch executes detailed analysis and processing:

 Extraction of sender, receiver, and ICN numbers from the payload.

 Correlation ID generation using sender-receiver-ICN as identifiers.

 Utilization of a data store to store correlation IDs and associated IDOC numbers.

Upon completion of the initial transaction, the EDI system asynchronously sends functional acknowledgments, necessitating meticulous handling:

EDI Partner to Functional Acknowledgment (FA):

o Messages from the EDI partner are directed to the FA process instead of the standard TPM iFlow.

o The custom iFlow bifurcates messages to preserve TPM functionality while accommodating additional logic:

o Identification of sender, receiver, and ICN details from the payload.

o Correlation ID generation and validation against stored IDOC numbers.

o Preparation of IDOC status messages using functional acknowledgment data fetched from the EDI system.

Before executing the aforementioned activities, preliminary groundwork was laid:

Preparation of MIG Objects and TPM Agreements:

o MIG objects for 997 X12 were meticulously crafted.

o TPM agreements were established within the Integration Suite B2B scenarios, configuring SAP S4 as the sender and EDI as the receiver.

This comprehensive approach ensures the seamless transmission of functional acknowledgments and addresses the complexities inherent in mapping solutions within SAP Integration Suite TPM v2 and EDI X12 943 4010 versions, facilitating streamlined communication between systems and enhancing operational efficiency.

3.1.2 Handling complex mapping for complex hierarchy of sender and receiver in process direct iflow

To address the second objective of handling complex mapping for intricate hierarchies of sender and receiver in the Process Direct iFlow, an elaborate strategy was devised. This section delineates the intricacies of the mapping process and the methodologies employed to ensure seamless integration between SAP Outbound IDOC structures and EDI X12 standards.

Understanding SAP Outbound IDOC Structure: DESADV DELVRY 07 and EDI X12 856_004010

o Comprehensive analysis of the SAP Outbound IDOC structure, specifically focusing on DESADV DELVRY 07.

o Examination of EDI X12 856_004010 standards, including HL segments for shipment, order, item, and packaging.

Understanding Segments and Child Elements:

o Analysis of E1EDL24 (items) and E1EDL37 (packaging) segments within the SAP IDOC.

o Exploration of child elements such as E1EDL44 and the relationship between items and packaging.

Conceptual Understanding of EDI X12 HL Segments:

o In-depth study of HL segments within EDI X12 standards, including their significance in representing hierarchical structures.

o Exploration of concepts such as Standard Pack (SOIP), Pick and Pack (SOPI), and their implications in mapping complexities.

Mapping Strategy for Complex Hierarchies:

Given the complexity of the sender and receiver hierarchies, a meticulous mapping strategy was devised within the Process Direct iFlow:

Message Processing in Custom iFlow:

Ingress of messages into the custom iFlow process direct adapter to initiate the mapping process.

Logical Division into Three Mappings:

1.Segmentation of the mapping logic into three distinct mappings to streamline the process:

• Business Logic Generation for HL Segments:

• Preparation of business logic to generate HL segments mirroring the SAP IDOC structure, with exceptions for HL sequence number and parent ID.

2.Hierarchical Structure Creation Using XSLT Logic:

• Development of XSLT logic to establish hierarchical structures, aligning with the EDI X12 standards.

3.HL Sequence and Parent Sequence Number Generation:

• Formulation of logic to generate HL sequence and parent sequence numbers, ensuring adherence to predefined guidelines.

Prerequisites and Preparation:

Prior verification of all necessary TPM agreements and MIG configurations in the Integration Advisor to facilitate seamless mapping.

In the mapping process, particular emphasis was placed on the Standard Pack (SOIP) methodology to ensure consistency and accuracy. The overarching objective is to streamline the mapping process, enabling efficient communication between SAP Outbound IDOC structures and EDI X12 standards while accommodating the complexities inherent in sender and receiver hierarchies.

3.2 DESCRIPTION OF DATA COLLECTION METHODS, INCLUDING SAMPLING TECHNIQUES

Data analysis techniques encompass qualitative content analysis and statistical analysis. Qualitative content analysis is employed to analyze textual data obtained from literature reviews, interviews, and case studies. This involves identifying themes, patterns, and trends related to B2B communication in the SAP ecosystem. Statistical analysis is utilized to evaluate quantitative data collected through surveys and empirical studies. Descriptive and inferential statistics are applied to assess the effectiveness and practicality of the proposed model framework.

Collection of data for Functional acknowledgement from EDI to SAP S4

To achieve the objectives of gathering data for both functional acknowledgments and mapping solutions, a structured approach was employed, encompassing various data collection methods and sampling techniques. This section elucidates the methodologies utilized to procure essential data sets for comprehensive analysis and mapping within the SAP Integration Suite environment.

Figure 20: Collecting all resource objects MIG/XSD, Groovy script for custom iflow.

Objective: Functional Acknowledgments

Scenario 1: SAP S4 Sends IDOC to SAP Integration Suite

Data Collection Approach:

• Got sample data from SAP S4 users for the sender IDoc DESADV. DELVRY07

• Prepared XSD from Integration advisor by creating MIG object for this SAP IDOC structure.

• Got sample data from EDI functional users for the X12 943_004010

• Prepared XSD from Integration advisor by creating MIG object for this EDI X12-943 -4010 structure.

• Used both these XSD in custom iflow while saving IDOC number in data store step against correlation id.

• Correlation id prepared from these variables using XPATH, getting payload from source system as follows.

• docType //S_GS/D_479; s //D_142,r //D_124 ,i //D_28,

• ${property.s}_${property.r}_${property.docType}_${property.i} as WLGORE_BTA_Correlationid;

• WLGORE_BTA_Correlationid prepared for Datastore object as below: <Idoc_Number>${header.SAP_EDI_Message_Number}</Idoc_Number>${property.s}_${property.r}_${property.docType}_${property.i};

• body <Idoc_Number>${header.SAP_EDI_Message_Number}</Idoc_Number>

• Utilized the Integration Advisor to create MIG (Mapping Implementation Guidelines) for both EDI and SAP IDOCs.

Scenario 2: EDI System Sends Functional Acknowledgment to SAP Integration Suite

Data Collection Approach:

• Got sample data from EDI funtional users for the sender EDI message X12-997-4010.

• Prepared XSD from Integration advisor by creating MIG object for this EDI X12 997 4010 structure.

• Used this XSD in custom iflow (/xsd/ASC-X12_997_004010.xsd) for functional acknowledgment receive.

• Prepared variables and contents from sender payload using XPATH functionality of content modifier.

• docType //S_AK1/D_479 ;body ${in.body},status1 //D_715,t //D_124,i //S_AK1//D_28,

• icn1 ${property.t}_${property.s}_${property.docType}_${property.i};

• Checking the correlation variable with Global datastore if any value found or not.

• If it is found fetching idoc number from it.

• And prepared IDOC STATUS functional acknowledgement to SAP system.

Logic used to prepare target SAP IDOC STATUS message as below logic:

<EDI_DC40 SEGMENT="1">

<IDOCTYP>SYSTAT01</IDOCTYP>

<MESTYP>STATUS</MESTYP>

<RCVPOR>SAPSS4</RCVPOR>

<REFINT>${property.IDocNum}</REFINT>

</EDI_DC40>

<DOCNUM>${property.IDocNum}</DOCNUM>

<STATUS>${property.status1}</STATUS>

<STATXT>${property.icn1}Success IdocNum:${property.IDocNum}</STATXT>

</E1STATS>

</IDOC>

</SYSTAT01>

Next , Modified the content status fields as per SAP understandable format.

Figure 21. In custom_iflow,Modified the STATUS field of IDOC as per SAP IDOC understandable format in the graphical mapping of integration suite.

Collection of data for Mapping solution from SAP S4 IDoc to EDI X12 :

Sample data collected for SAP S4 IDOC DESADV ZDELVRY07 from SAP functional consultants.

Also collected sample data for EDI X12 856 4010V from EDI functional people.

Prepared XSD from Integration advisor from library function features and created corresponding MIG objects for these two.

Got business logic as mapping sheet from business owners to map both source and target structures for this.

Applied required mapping logic in between source target in custom iflow, where logic has been divided into 3 sections. First one deal with business logic , second one deal with hierarchy SOIP as per stand pack format of EDI X12-856 4010, finally third logic, i.e. generating HL sequence number and HL segment parent segment id generation in graphical mapping using array list concept.

Execution: Custom iFlows were integrated into comprehensive test environments to evaluate their performance under varying load conditions.

Criteria: Integration tests validated the seamless transmission of messages, accurate mapping transformations, and proper handling of functional acknowledgments.

Regression Testing:

Objective: To ensure that the introduction of new solutions did not inadvertently impact existing functionalities.

Approach: Regression testing involved re-executing previously conducted test cases to validate system stability and reliability.

Execution: Test scenarios covering critical integration pathways were re-run to identify any regression issues introduced by recent changes.

Criteria: Regression tests focused on detecting anomalies or deviations from expected behaviors, ensuring the integrity of the overall system.

Performance Testing:

Objective: To evaluate the performance and scalability of the solutions under varying load conditions.

Approach: Performance testing involved simulating high-volume transaction scenarios to measure system response times and throughput.

Execution: Load testing tools were employed to simulate concurrent user interactions and message transactions.

Criteria: Performance tests measured system responsiveness, resource utilization, and transaction throughput, ensuring that the solutions could handle peak loads efficiently.

User Acceptance Testing (UAT):

Objective: To validate that the solutions meet the requirements and expectations of end-users and stakeholders.

Approach: UAT involved engaging end-users and stakeholders in executing predefined test cases and scenarios.

Execution: End-users evaluated the solutions based on their usability, functionality, and alignment with business objectives.

Criteria: UAT focused on gathering feedback from end-users regarding system usability, intuitiveness, and effectiveness in addressing business needs.

Through the comprehensive application of these testing methodologies, the solutions devised for handling functional acknowledgments and mapping complexities underwent rigorous validation, ensuring their robustness, reliability, and effectiveness in real-world integration scenarios.

End of XSLT Code

To apply logic from EDI format (list of items, list of packing information) structure to generate the SOIP format using the provided XSLT code, let's break down the code and explain how each section contributes to the transformation:

1. Root Template:

<xsl:template match="/">: This template matches the root element of the XML document and initiates the transformation process.

2. Main Transformation Logic:

<M_856>: This element represents the start of the SOIP format.

<xsl:apply-templates select="M_856/*" />: It applies templates to child elements of the root element M_856.

3. Matching Specific Elements:

<xsl:template match="S_ST">, <xsl:template match="S_BSN">, <xsl:template match="S_DTM">: These templates match specific segments (S_ST, S_BSN, S_DTM) and copy them as they are to the output.

<xsl:template match="G_HL[S_HL/D_735='S']">: Matches a group (HL) where the hierarchical level (D_735) equals 'S'. This likely represents a shipment in the EDI structure.

<xsl:template match="G_HL[S_HL/D_735='O']">: Matches a group (HL) where the hierarchical level (D_735) equals 'O'. This may represent an order in the EDI structure.

<xsl:template match="G_HL[S_HL/D_735='I']">: Matches a group (HL) where the hierarchical level (D_735) equals 'I'. This likely represents an item in the EDI structure.

Within this template, there's a loop (<xsl:for-each>) that selects related packing information (G_HL[S_HL/D_735='P']) for the current item.

4. Matching Control Segments:

<xsl:template match="S_CTT">: Matches the control total segment and copies it as is.

<xsl:template match="S_SE">: Matches the transaction set trailer segment and copies it as is.

5. Default Template:

<xsl:template match="text()">: Matches any text nodes and does nothing. This ensures that text nodes are ignored during the transformation.

Explanation:

The XSLT code provided is designed to transform EDI data into an SOIP format. It identifies and processes different segments such as shipment, order, and item levels based on their hierarchical levels.

It maintains the structure of the input EDI data while copying relevant segments into the output SOIP format.

The logic within each template ensures that only the necessary segments are included in the output, facilitating the conversion process from EDI to SOIP format.

Algorithm for Generating HL Sequence:

• Part3: Developed an algorithm for generating HL sequence numbers for parent nodes.

• Utilized UDF (User Defined Function) to calculate D_735 (segment qualifier) and D_628 (sequence number) as input queue values.

Validated the algorithm to ensure accurate generation of HL sequence numbers for parent nodes.

Figure 28. Mapping implemented in 3rd Graphical mapping to generate HL segment sequence Number.

Figure 29. Mapping implemented in 3rd Graphical mapping to generate HL segment parent node sequence Number.

Test Cases and Validation:

Implemented various test cases to validate the mapping solutions:

• Ensured all mandatory fields are provided in the transformed data.

• Checked for missing mandatory fields and assigned default values if necessary.

• Validated the functional correctness and technical validity of the mapped data against XSD schemas.

• Tested for any potential memory or performance issues during data transformation.

• Verified the test data received from users against the expected data format.

The rigorous analysis conducted on the collected data from SAP users and EDI users ensures the efficacy and reliability of the mapping solutions implemented within the SAP Integration Suite environment. By adhering to stringent validation processes and comprehensive testing methodologies, the mapping solutions are poised to facilitate seamless integration and optimal performance between SAP S4 and the EDI system, thereby enhancing operational efficiency and data accuracy.

EDI FUNCTIONAL ACKNOWLEDGEMENT FORMAT.

X12 997

The ANSI X12 997 example demonstrates a positive functional acknowledgement sent by a supplier to acknowledge a purchase order. The 997 sent depends on the GS and ST segments in the 850.

For example, if you received the following 850:

ISA*00* *00* *ZZ*ARIBAEDI *ZZ*284010872 *030415*1314*U*00401*000601828*0*T*>~

AK1*PO*000341217~

AK2*850*0001~

AK5*A~

AK9*A*1*1*1~

SE*6*0001~

ST*997*0001~ ; Start Transaction Set (ST) segment indicating the beginning of the Functional Acknowledgment (997) message. '0001' is the control number.

AK1*PO*000341217~ ; Acknowledgment Level 1 (AK1) segment provides information about the transaction set being acknowledged. In this case, it's a Purchase Order (PO) with the control number '000341217'.

AK2*850*0001~ ; Acknowledgment Level 2 (AK2) segment specifies the type of transaction set being acknowledged and its control number. '850' indicates that it's an EDI Purchase Order (850) and '0001' is its control number.

AK5*A~ ; Acknowledgment Level 5 (AK5) segment indicates the acknowledgment code. 'A' typically signifies that the transaction set was accepted without errors.

AK9*A*1*1*1~ ; Acknowledgment Level 9 (AK9) segment provides summary information about the acknowledgment. Here, 'A' indicates acceptance, followed by counts of accepted, rejected, and accepted with errors segments, all set to '1'.

SE*6*0001~ ; End Transaction Set (SE) segment marks the end of the Functional Acknowledgment (997) message. '0001' matches the control number specified in the ST segment.

Reject case:

ST*997*0001~

AK1*PO*000341217~

AK2*850*0001~

AK5*R~

AK9*R*1*1*1~

ST*997*0001~ ; Start Transaction Set (ST) segment indicates the beginning of the Functional Acknowledgment (997) message. '0001' is the control number.

AK5*R~ ; Acknowledgment Level 5 (AK5) segment indicates the acknowledgment code. 'R' typically signifies rejection.

AK9*R*1*0*0~ ; Acknowledgment Level 9 (AK9) segment provides summary information about the acknowledgment. Here, 'R' indicates rejection, followed by counts of accepted, rejected, and accepted with errors segments, all set to '0'.

SE*5*0001~ ; End Transaction Set (SE) segment marks the end of the Functional Acknowledgment (997) message. '0001' matches the control number specified in the ST segment.

UNT+3+1'

UNZ+1+1'

the statements commonly found in EDI payload messages, specifically focusing on acceptance and rejection acknowledgments:

UNB (Interchange Header):This segment marks the beginning of the interchange and contains information about the sender, receiver, timestamp, and control reference numbers.

UNH (Message Header):Marks the beginning of a specific message within the interchange. It includes details such as the message type, version, release, and control reference numbers.

UCI (Functional Acknowledgment):This segment is used in EDI CONTRL messages to provide acknowledgment information. It includes details such as the control reference numbers of the sender and receiver, as well as an acknowledgment code indicating acceptance, rejection, or other statuses.

UNT (Message Trailer):Marks the end of the specific message. It includes a segment count and a control reference number that must match the values specified in the UNH segment.

UNZ (Interchange Trailer):Marks the end of the interchange. It includes a count of the messages transmitted in the interchange and a control reference number.

Now, let's discuss the acceptance and rejection acknowledgment messages:

Acceptance Acknowledgment: In an acceptance acknowledgment, the UCI segment typically includes acknowledgment codes indicating that the message has been successfully received and processed by the receiver. The acknowledgment code '8' is commonly used to indicate acceptance.

Rejection Acknowledgment: In a rejection acknowledgment, the UCI segment includes acknowledgment codes indicating that the message has been rejected due to errors or issues encountered during processing. The acknowledgment code '4' is commonly used to indicate rejection.

These acknowledgments provide feedback to the sender about the status of their transmitted messages, allowing them to track and manage the EDI communication effectively. The acknowledgment codes help both parties understand whether the transmitted messages were successfully processed or if there were any issues that need to be addressed.

SAP CPI groovy code [28][40][43][46] to validate both Functional acknowledgment sand prepare property variables for further processing.

Algorithm Analysis: Processing EDI Acknowledgement in SAP Standard iFlow

Step 1: Message Processing Initialization

The script initializes variables necessary for message processing, such as fackMessage, headers, fackMessageType, segmentArray, senderTradingPartnerId, receiverTradingPartnerId, and interchangeNumber.

The type of EDI message is identified based on the value of SAP_EDI_Message_Type in the headers.

Step 2: Handling EDI Functional Acknowledgements

If the message type is "997" (Functional Acknowledgement for X12), the script:

Parses segments using delimiters.

Identifies segments related to ISA, AK1, and AK9.

Retrieves sender and receiver trading partner IDs from the ISA segment.

Retrieves the interchange number from the AK1 segment.

Determines the action code from the AK9 segment and sets properties accordingly.

Step 3: Handling EDIFACT Functional Acknowledgements

If the message type is "CONTRL" (Functional Acknowledgement for EDIFACT), the script:

Normalizes message formatting by removing whitespaces and special characters.

Parses segments using delimiters specific to UNA or default delimiters.

Identifies the UCI segment.

Retrieves interchange number, sender, and receiver trading partner IDs from the UCI segment.

Determines the action code and sets properties accordingly.

Step 4: Correlation ID and Property Setting

Sets correlation-related properties using extracted information.

These properties include sender and receiver trading partner IDs and the interchange number.

Step 5: Return Message

Returns the processed message with added properties for correlation and action code.

Conclusion of groovy script analysis to consume the EDI acknowledgement payload and prepare variables from it.

The provided Groovy script processes SAP standard iFlows for handling EDI functional acknowledgements. It distinguishes between X12 and EDIFACT acknowledgements, extracts necessary information such as sender and receiver details, interchange number, and action codes, and sets properties for correlation and action handling. Additionally, it ensures proper parsing of segments using appropriate delimiters and normalization of message formats. Overall, the script provides a comprehensive solution for processing EDI acknowledgements in SAP environments.

5 DATA INTERPRETATION

5.1 INTERPRETATION OF THE ANALYZED DATA TO IDENTIFY ROOT CAUSES AND PATTERNS

Objective 1: Analysis of Standard TPM iFlows and Custom iFlow Creation

Upon thorough analysis of the standard TPM iFlows provided by SAP, it was observed that a crucial section for connecting to SAP S4 to send "IDoc status" messages from the Integration Suite was missing. To address this gap, the necessity of creating a custom iFlow became evident.

The custom iFlow required two distinct scenarios/logic to effectively handle the integration process:

Scenario/Logic 1: When sending output data from the TPM iFlow to the EDI system, it was imperative to bifurcate the flow into two branches. One branch was dedicated to the EDI system, while the other branch was designed to store the IDoc number from the source payload (SAP S4 IDoc) against a correlation ID. The correlation ID was prepared using the source and target partner IDs along with the interchange number.

Scenario/Logic 2: Upon receiving functional acknowledgments from the EDI system, the custom iFlow was configured to multicast the payload into two branches. One branch directed the payload back to the TPM iFlows, while the other branch was responsible for sending the functional acknowledgment to SAP S4 as an IDoc. This branch utilized correlation ID matching logic, where the correlation ID was prepared from the source payload, source, and target partner IDs, and the interchange number.

Custom iflow :

Figure 32: Custom iflow to send Functional acknowledgment to SAP S4.

Upon thorough analysis of the standard TPM iFlows provided by SAP, a significant gap was identified in the absence of a section for connecting to SAP S4 to send "IDoc status" messages from the Integration Suite. To address this gap effectively, a custom iFlow was developed with a comprehensive approach comprising two distinct scenarios/logic.

Scenario 1: Store IDoc Number against correlation id .

In the first scenario, messages were received from the TPM iFlow via Process Direct Integration. Upon reception, a multicast operation was implemented to bifurcate the flow into two branches.

Branch 1: Validating FA Parameters: This branch validated specific EDI partner lists requiring functional acknowledgments. If true, the logic was applied to convert EDI to XML format, prepare variables, and fetch values from the payload to create a correlation ID and IDoc number. The correlation ID was prepared using XPath expressions such as //S_GS/D_479, //D_142, //D_124, //D_28, and ${property.s}${property.r}${property.docType}_${property.i}. The IDoc number was extracted from the message header and stored using a write step with appropriate retention settings.

Branch 2: Forwarding to EDI System: Messages were forwarded to the EDI system via the AS2 channel for further processing.

Scenario 2: Fetch IDoc Number against correlation id and send Functional acknowledgment to SAP S4 via IDoc STATUS.

After some time, the EDI system responded to the SAP Integration Suite with functional acknowledgments (positive or negative) based on the message processing state. AK5 and AK9 segments determined the acknowledgment status, denoted by 'A,' 'R,' or 'P.'

Upon receipt of functional acknowledgments, a custom iFlow (common for both scenarios) was triggered via HTTP receiver. The iFlow executed a multicast operation to divide the flow into two branches.

Branch 1: Forwarding to TPM iFlow: Messages were forwarded to the TPM iFlow to leverage standard features of B2B monitoring for functional acknowledgments within the Integration Suite.

Branch 2: Applying Logic for Acknowledgment: Using a Groovy script, variables were prepared to determine if EDI partners expected functional acknowledgments. If affirmative, the logic was applied to convert EDI to XML, extract correlation variables from the source payload, fetch the IDoc number from the data store if found, and map the IDoc status message with AK5 and AK9 segments to IDoc segments as per SAP's mapping logic.

By implementing both scenarios in the custom iFlow, the functionality of sending functional acknowledgments to SAP S4 was successfully achieved, enhancing the integration process between the TPM iFlow and SAP S4. This comprehensive approach ensures seamless communication and efficient handling of IDoc status messages within the Integration Suite.

Objective 2: Mapping Logic for Complex Mapping like EDI 856 SOIP

During the research phase, it was identified that SAP did not provide a mapping template for complex mappings like EDI 856 SOIP (Standard Pack), along with other packaging mechanisms such as SOPI. Focusing specifically on SOIP, it was determined that the mapping logic could be achieved through the Process Direct Integration iFlow, instead of using the Integration Advisor.

In the custom iFlow developed for this purpose, the mapping logic was divided into three distinct sections:

Graphical Mapping: This section applied the necessary business logic to generate hierarchical level (HL) segments similar to the SAP IDoc structure.

XSLT Mapping: Responsible for generating the SOIP format, this section omitted the HL sequence number and parent ID sequence number generation.

Sequence Number Generation Logic: Finally, this section was dedicated to preparing the logic for HL segment sequence and parent sequence number generation, ensuring the proper structuring of the SOIP format.

In conclusion, the interpretation of the analyzed data led to the identification of key gaps and requirements in the integration process, ultimately guiding the development of custom iFlows and mapping logic to address these needs effectively. Through meticulous analysis and strategic planning, the integration processes were optimized for enhanced efficiency and seamless data exchange between systems.

Algorithm for XSLT mapping and code

Match Root Element and Apply Templates:

Match the root element '/' and create the 'M_856' element.

Apply templates to its child elements.

Match Specific Elements and Copy:

Match elements such as 'S_ST', 'S_BSN', 'S_DTM', 'S_CTT', and 'S_SE'.

Copy the matched elements as they are without any transformation.

Match G_HL Elements with Specific Criteria:

Match 'G_HL' elements where the 'S_HL/D_735' equals 'S' or 'O'.

Copy the matched elements as they are.

Match G_HL Elements with 'I' Criteria and Apply Logic:

Match 'G_HL' elements where the 'S_HL/D_735' equals 'I'.

Copy the matched 'G_HL' elements as they are.

For each matched 'G_HL' element, find related 'G_HL' elements where 'S_HL/D_735' equals 'P' and 'S_LIN/D_350' equals the current 'S_LIN/D_350' element.

Copy the matched 'G_HL' elements.

Match Text Nodes:Match any text nodes and do nothing.

This XSLT mapping serves to selectively copy and transform elements based on specific criteria defined in the match patterns. It provides a structured approach to transforming XML data while maintaining the integrity of the original structure.

5.2 ASSESSMENT OF THE EFFECTIVENESS OF THE PROPOSED SOLUTION COMPONENTS

In this section, we evaluate the effectiveness of the proposed solution components, focusing on enhancing custom iFlows for TPM standard package iFlows and designing custom mapping solutions for typical X12/EDIFACT/SAP IDoc mapping, specifically ASN (Ship Notice) and Packaging Structures.

Objectives:

Enhancing Custom iFlow for TPM Standard Package iFlows:

The primary objective is to design and implement custom iFlows within the SAP Integration Suite's TPM V2 package. These iFlows aim to support seamless processing of EDI messages and facilitate reliable B2B communication. The objectives include:

Custom iFlow Creation:

Logic 1: Implementing functionality to save IDoc number, sender, receiver, and ICN (Interchange Number) when sending messages from SAP TPM to EDI systems.

Logic 2: In response to messages from the EDI system to the Integration Suite, diverting the message to a custom iFlow instead of TPM iFlows. Checking the datastore for any IDoc number for correlation ID prepared from sender, receiver partner, and ICN in the EDI payload. If found, sending an IDoc status message to SAP S/4HANA.

Integration of TPM Agreements, MIG, and MAG Objects:

Integrating TPM agreements, Master Integration Guide (MIG), and Master Agreement Guide (MAG) objects within the Integration Advisor. This integration aims to streamline the agreement creation process and ensure compatibility with SAP S/4HANA and EDI partners.

5.3 INTERPRETATION OF TEST RESULTS AND IMPLICATIONS FOR SYSTEM PERFORMANCE

In this section, we analyze the results obtained from testing the custom iFlows developed as part of enhancing the TPM (Trading Partner Management) Standard Package iFlows within the SAP Integration Suite. The objectives of this enhancement were twofold:

Enhancing Custom iFlow for TPM Standard Package iFlows:

The primary objective was to design and implement custom iFlows to support the seamless processing of Electronic Data Interchange (EDI) messages and facilitate reliable Business-to-Business (B2B) communication. This involved the creation of custom logic and functionality to enable the generation and transmission of functional acknowledgments (positive and negative) from the custom iFlow to the SAP S/4HANA system via IDoc status messages. Additionally, the objective included the integration of TPM agreements, Master Integration Guide (MIG), and Master Agreement Guide (MAG) objects within the Integration Advisor to streamline the agreement creation process and ensure compatibility with SAP S/4HANA and EDI partners.

Designing Custom Mapping Solutions for Typical X12/EDIFACT/SAP IDoc Mapping: ASN (Ship Notice) and Packaging Structures:

The secondary objective aimed to design custom mapping solutions within the SAP Integration Suite's TPM framework to facilitate seamless data transformation and mapping between SAP IDoc structures and EDI formats (e.g., X12, EDIFACT). This included creating graphical mappings to validate output as per EDI requirements, implementing XSLT logic to convert SAP IDoc items and packs to the Standard Output Interchange Protocol (SO IP) format, and designing graphical mappings to achieve hierarchical segment generation for sequence and parent ID generation. The goal was to enhance the mapping process, improve data accuracy, and ensure compliance with EDI standards and requirements.

Implementation:

Objective 1: Custom iFlow Creation:

Logic 1: During message transmission from SAP TPM to the EDI system, the custom iFlow saves the IDoc number, sender, receiver, and Interchange Control Number (ICN) in a datastore.

Logic 2: Upon receiving a response message from the EDI system, the message is routed to the custom iFlow instead of the TPM iFlows. The custom iFlow checks the datastore for any IDoc number corresponding to the correlation ID prepared from the sender, receiver partner, and ICN extracted from the EDI payload. If found, it sends an IDoc status message to SAP S/4.

Objective 2: Creating Custom iFlow:

Divide Mapping Logic into 3 Parts:

Apply business logic from SAP IDoc to EDI.

Implement XSLT logic to prepare the SO IP format (Standard Package) from SAP IDoc items and packs.

Design graphical mapping for hierarchical segment generation for current and parent IDs using User-Defined Functions (UDF) such as ArrayList.

Implications for System Performance:

The implementation of custom iFlows has demonstrated improved efficiency in processing EDI messages and facilitating B2B communication.

Integration of TPM agreements, MIG, and MAG objects has streamlined agreement creation processes and enhanced compatibility with SAP S/4HANA and EDI partners.

Custom mapping solutions have resulted in better data accuracy, compliance with EDI standards, and optimized performance in data transformation and mapping processes.

In conclusion, the enhancements made to the TPM Standard Package iFlows have positively impacted system performance, resulting in more efficient B2B communication and streamlined integration processes. Further analysis and optimization may be required to ensure continued performance improvements.

6 RESULT AND DISCUSSION

6.1 PRESENTATION OF THE RESULTS OF UNIT AND INTEGRATION TESTING

Integration testing results: the process of handling positive and negative functional acknowledgments (FA), let's break down the scenario:

IDoc Payload Outbound from SAP S4 (Sender): This is the initial outbound IDoc payload sent from SAP S4 to the middleware or SAP Integration Suite [19][20][21][24].

It contains delivery-related information such as delivery number, shipping details, and other relevant data.

Middleware Logic Implementation: Custom iFlow logic is implemented in the middleware (SAP Integration Suite) to process the inbound IDoc payload.

This logic includes handling various scenarios such as mapping the SAP S4 IDoc format to the target EDI format (in this case, EDI 943 4010 version), validating data, and preparing it for transmission to the EDI partner.

Positive Functional Acknowledgment (FA): After receiving the IDoc payload, the middleware processes it and sends it to the EDI partner.

Upon successful receipt and processing of the payload, the EDI partner generates a positive FA, indicating that the document was received and accepted.

The positive FA typically contains details confirming the receipt of the document, including the IDoc number (in this case, <DOCNUM>0000000000798081) and any additional acknowledgment information.

In the provided XML snippet, the <STATUS>16</STATUS> indicates a positive acknowledgment.

Negative Functional Acknowledgment (FA): If there are errors or issues during the processing of the IDoc payload, the EDI partner may generate a negative FA.

A negative FA indicates that the document was not accepted due to errors or discrepancies.

The negative FA typically includes details about the errors encountered and may provide guidance on how to resolve them.

In the XML snippet, if the <STATUS> were 17, it would indicate a negative acknowledgment.

Handling of FA in Middleware: The middleware receives the FA from the EDI partner and processes it accordingly.

For positive FAs, it may log the acknowledgment details and proceed with further processing.

For negative FAs, it triggers error handling routines to address the issues and may notify appropriate stakeholders for resolution.

Presentation of Integration Testing Results: In the context of presenting the results of integration testing, you would include information about the successful transmission of IDoc payloads, reception of positive FAs, and handling of any negative FAs encountered during testing. This section would detail the performance of the custom iFlow logic, including how it successfully handles positive FAs and appropriately manages errors and exceptions.

Overall, the successful implementation of custom iFlow logic alongside standard integration packages demonstrates effective handling of IDoc transmissions and acknowledgment processing in the SAP integration landscape.
