Title: Enhancing B2B Communication in SAP Ecosystem: A Model Framework for Reliable EDI Processing - Part 2: Solving Mapping Issues in SAP Integration Suite; Hint: "TYPICAL X12/EDIFACT/SAP IDOC MAPPING: ASN (SHIP NOTICE) AND PACKAGING STRUCTURES One of the most complex things you can encounter working on the maps is the mapping of hierarchical (nested) packages/products in ASNs (Ship Notices). Things like partners, dates or references usually are straight-forward and in a lot of cases you can use simple direct connections. But different formats use different approaches when it comes to hierarchical (nested) structures. So, let me show you how X12, EDIFACT and IDocs describe this: one container C1 with 5 pallets, 2 pallets (P1 and P2) are for Product A, 2 pallets (P3 and P4) are for Product B and 1 pallet (P5) is a mixed load with Product A and Product C C1 P1 Product A, 100 KGM P2 Product A, 100 KGM P3 Product B, 90 KGM P4 Product B, 90 KGM P5 Product A, 20 KGM Product C, 90 KGM So, all mentioned formats (X12, EDIFACT and SAP IDoc) are able to describe products, containers/packages, and relationship between these entities. SAP IDoc (DELVRY/SHPMNT) Let’s start with SAP IDocs, DELVRY05 (if you familiar with SAP IDocs, you know that the same approach is used in SHPMNTs). There are 2 “parallel” (or sibling) structures for products and HUs (handling units), E1EDL24 and E1EDL37 respectively. Relationships between products and packages, as well as packaging hierarchical structure (parent/children HUs) are described with E1EDL37 / E1EDL44. How products and packages which contain this product are connected: E1EDL24 <<< product POSNR = 000010 MATNR = Product A LFIMG = 220 VRKME = KG E1EDL37 <<< package (pallet) EXIDV = P1 E1EDL44 <<< connection between products and packages POSNR = 000010 VEMNG = 100 VEMEH = KG MATNR = Product A ------------------ As you can see, E1EDL44 contains information about the product it contains (POSNR, MATNR; CHARG for batch splits) and its amount in this container (VEMNG and VEMEH for UoM) – the total amount of Product A is 220 KGM but pallet P1 contains only 100 KGM of it. --------- How packages and containers which contain these packages are connected: E1EDL37 <<< package (container) EXIDV = C1 E1EDL44 <<< connection between this container and packages it contains EXIDV = P1 E1EDL37 <<< package (pallet) EXIDV = P1 -------------- In this case E1EDL44 in the parent HU uses EXIDV to connect container C1 and pallet P1. Since there are “intermediate” packages between container and products, E1EDL37 which describes container doesn’t have any direct information about the products it contains. So, in IDocs (DELVRY) parent structure E1EDL37 refers to its children via E1EDL44. The E1EDL44 is a repeatable structure, there will be multiple E1EDL44s under E1EDL37 if it contains more than one children (packages or products). Our delivery example will be described like this: E1EDL24 POSNR = 000010 MATNR = Product A E1EDL24 POSNR = 000020 MATNR = Product B E1EDL24 POSNR = 000030 MATNR = Product C E1EDL37 EXIDV = C1 E1EDL44 EXIDV = P1 E1EDL44 EXIDV = P2 E1EDL44 EXIDV = P3 E1EDL44 EXIDV = P4 E1EDL44 EXIDV = P5 E1EDL37 EXIDV = P1 E1EDL44 POSNR = 000010 MATNR = Product A E1EDL37 EXIDV = P2 E1EDL44 POSNR = 000010 MATNR = Product A E1EDL37 EXIDV = P3 E1EDL44 POSNR = 000020 MATNR = Product B E1EDL37 EXIDV = P4 E1EDL44 POSNR = 000020 MATNR = Product B E1EDL37 EXIDV = P5 E1EDL44 POSNR = 000010 MATNR = Product A E1EDL44 POSNR = 000030 MATNR = Product C ------------- X12 (856) In X12, 856 document is used for ASNs. It contains a special repeatable structure – HL group, which is used to organise hierarchical relationships. Here let me make a brief digression. In my opinion, X12 is little bit more flexible comparing with IDoc or EDIFACT, and here you could meet such terms as “Pick and Pack” (aka SOPI) and “Standard Pack” (also referenced as SOIP). I think it might be useful to review them. HL segment contain HL-03 element – “Hierarchical Level Code”, and in 99% cases it is one of S (Shipment), O (Order), T (Tare), P (Pack) or I (Item). First level in X12 ASNs is always S (Shipment), i.e. it contains data, common for this shipment (delivery). Next level is O (Order) and it contains information about PO this Shipment refers to. Even though X12 allows you to have multiple Orders under the same Shipment, this option is almost never used (for example, I have had only one case) and again, in 99% cases there is only one Order under Shipment. Structures “under” Order depends on the type of packaging and products used. Typical structure is Pick and Pack, or SOPI (or SOTPI, if you need to describe a container). You might already guess that P and I in “SOPI” are for Pack and Item respectively. If so – you are absolutely right. SOPI structure has the following implementation in X12: SOPI (Pick and Pack) HL (S) <<< Shipment HL (O) <<< Order HL (P) <<< Package HL (I) HL (P) <<< mixed load (2 products in one pack) HL (I) HL (I) SOPI structure is ideal for describing packages which are different from each other – different weights, mixed loads (multiple products per package). But what if you have multiple “homogeneous” packages, which contain only one products and are the same except of their IDs (package IDs or labels or SCC codes) ? SOPI structure might be too cumbersome (but still you can use it – no problems!) – if you have 100 packages you would need to repeat HL (P) – HL (I) pairs 100 times, and the only difference between them would be package IDs. For such cases it is easier to use SOIP structure ------------ SOIP (Standard Pack) HL (S) <<< Shipment HL (O) <<< Order HL (I) <<< Product HL (P) <<< Package MAN <<< used for Package IDs, repeatable so, there will be only one HL (I) for product and one HL (P) for all the same packages with this product. Repeatable MAN segment will be used for all the package IDs. More complex nested packaging structures might be easily described with nested HLs – if you need containers it might be this about literature; solution: custom process direct iflow for mapping solution instead of MAG object in TPM b2b transaction; in this custom iflow: Graphical mapping1 + XSLT mapping + Graphical mapping2; in first graphical mapping1 : just map logic from idoc to edi( as similar generte 4 G_HL segments in edi, 1st is shipment, 2nd is for order, 3rd is for items(o. unbounded), 4th is pages (o..unbounded); next xslt logic , modify all packages inside of item those are correlated to item number; thus achieveing SOI[p1,p2,p3...] ,I[p1,p2,p3...]..... ;finally generating sequence for G_HL/D_628 (hl sequence number starts from 1 ), next G_HL/D_734 ( sequence number for parent id) using normal grpahical mapping ,using udf for 2 fileds , remaining fields are passthrow; used array list navigation ; udf code for as below ; def void HL_ParentID_Counter(String[] input, String[] input2, Output output, MappingContext context) { int c1 = 0; for (int i = 0; i < input.length; i++) { if (input[i] != null && input[i].trim().length() > 0 && input[i].equals("P") && input[i - 1].equals("I")) { output.addValue(Integer.parseInt(input2[i]) - 1); c1 = Integer.parseInt(input2[i]) - 1; } else if (input[i] != null && input[i].trim().length() > 0 && input[i].equals("P") && input[i - 1].equals("P")) { output.addValue(c1); } else if (input[i] != null && input[i].trim().length() > 0 && input[i].equals("O")) { output.addValue("1"); } else if (input[i] != null && input[i].trim().length() > 0 && (input[i].equals("I") && input[i - 1].equals("O")) || (input[i].equals("I") && input[i - 1].equals("P"))) { output.addValue("2"); } else { output.addValue(""); } } }; by having this information. provide Abstract section content for the above?

Abstract:

Efficient B2B communication within SAP ecosystems demands robust mapping solutions to handle complex hierarchical structures inherent in EDI transactions. In this paper, we address the challenge of solving mapping issues within SAP Integration Suite, focusing on typical X12/EDIFACT/SAP IDoc mapping scenarios, particularly in Advanced Ship Notice (ASN) and packaging structures.

The complexity of ASN mappings lies in representing hierarchical relationships between containers, pallets, and products across different formats. We delve into the description of hierarchical structures in SAP IDocs (DELVRY/SHPMNT) and compare them with X12 (856) standards, showcasing the nuances in mapping product and package relationships.

Drawing from literature review and practical experience, we propose a custom mapping solution to address mapping challenges, replacing the MAG object in TPM B2B transactions. Our custom iFlow solution employs Graphical Mapping, XSLT Mapping, and further Graphical Mapping to achieve seamless transformation of IDoc to EDI structures.

In the first graphical mapping stage, we generate hierarchical segments (G_HL) to represent shipments, orders, and items, adapting to the SOIP (Standard Pack) or SOPI (Pick and Pack) structures as per requirements. Subsequent XSLT logic modifies package details correlated to item numbers, facilitating the generation of SOI[p1,p2,p3...] and I[p1,p2,p3...] sequences.

Our custom mapping solution incorporates Array List Navigation and User-Defined Functions (UDF) to manage parent ID sequences efficiently, ensuring accurate mapping of hierarchical relationships. The UDF dynamically assigns parent IDs based on package and item correlations, enhancing mapping accuracy and reliability.

By addressing mapping challenges with a custom mapping solution, organizations can streamline B2B communication processes and achieve greater interoperability within SAP ecosystems. Our findings contribute to the optimization of mapping strategies and offer practical insights for organizations seeking to enhance EDI processing capabilities within SAP Integration Suite environments.

Introduction:

Efficient Business-to-Business (B2B) communication within SAP ecosystems is essential for organizations to streamline operations and maintain competitive advantages in today's digital landscape. Central to this communication are Electronic Data Interchange (EDI) transactions, which facilitate the exchange of structured data between trading partners. However, handling complex hierarchical structures in EDI mappings poses significant challenges for organizations operating within SAP environments.

One of the most intricate aspects of EDI mappings involves the representation of hierarchical packaging structures, particularly in Advanced Ship Notice (ASN) transactions. Different EDI standards such as X12, EDIFACT, and SAP IDoc employ distinct approaches to describe hierarchical relationships between containers, pallets, and products. Understanding and mapping these structures accurately are paramount to ensure seamless data exchange and interoperability across diverse systems.

In this paper, we delve into the complexities of typical X12/EDIFACT/SAP IDoc mappings, focusing on ASN and packaging structures. We explore how various formats describe hierarchical relationships and highlight the challenges organizations face in mapping these structures within SAP Integration Suite environments.

Drawing from practical experience and literature review, we propose a custom mapping solution to address mapping challenges and enhance B2B communication reliability within SAP ecosystems. Our solution replaces the MAG object in Trading Partner Management (TPM) B2B transactions, offering a flexible and scalable approach to handle intricate mapping requirements.

Through a combination of Graphical Mapping, XSLT Mapping, and further Graphical Mapping stages, our custom iFlow solution facilitates seamless transformation of SAP IDoc data to EDI structures, accommodating diverse hierarchical representations across different formats. We present a detailed overview of the mapping process, including the adaptation to SOIP (Standard Pack) or SOPI (Pick and Pack) structures, and the dynamic management of parent ID sequences using User-Defined Functions (UDF).

By addressing mapping challenges with a custom mapping solution, organizations can optimize EDI processing workflows, improve data accuracy, and foster stronger B2B relationships within SAP ecosystems. Our study contributes to the growing body of knowledge on EDI mapping strategies, offering practical insights and recommendations for organizations navigating the complexities of B2B communication within SAP Integration Suite environments.

In the subsequent sections, we delve deeper into the intricacies of ASN mappings and packaging structures, presenting our custom mapping solution and discussing its implications for enhancing B2B communication reliability and efficiency within SAP ecosystems.
