Conquering the unknown world between two SAP ERP systems

SAP systems back some of the world’s largest supply chains. Porsche, BASF, EDEKA and the like heavily rely on the use of SAP to realize their procurement and sales processes. For most SAP developers, however, the perceived world usually ends at the SAP system’s boundaries.  

In this talk we will explore the unknown land, which we must conquer in order to connect two ERP systems. We examine the technical protocols such as AS2, X.400, OFTP2, etc., give an overview of the concept of Value Added Networks (VAN), and show the particularities of different industries, taking automotive and retail as an example. Furthermore, we introduce the different standards and their ideas such as VDA, EDIFACT, ANSI ASC X12, etc. and show why XML is not always the better choice. 

Finally, we show the technical challenges we have to master in an SAP system in order to get the necessary information in and out of the system using IDocs. After this talk you should have a thorough understanding of the previously unknown world between two ERP systems.

@Timo_John (SCN)Code Noise and the shared Kernel

Code for error handling and logging is necessary, but not the core part of a development objet. In some cases it eats up so much space that it will be hard for developers to find the relevant places where the magic happens.

Use ABAP language features to get rid of code noise that distracts you from inspecting and understanding the business code.

We build a tools set to overcome this hurdle and to enforce similarity in code we build a so called shared kernel that helps developers to solve problems in the same way - always - any system. This helpes the next developer to understand the code faster.

SQL Anywhere Forum

SAP IQ - Business Intelligence and vertical data processing with 8 GB RAM or lessSAP IQ is a HANA companion for Smart Data Access / Integration and SAP BW NLS, to keep data way beyond memory limits accessible. But it also is a full-blown data warehouse system of its own, with column oriented data storage and powerful analytics capabilities. It can scale up to the world's largest data warehouse and down to desktop or notebook computers. This session is intended to show the benefits and capabilities of the vertical data structures used inside and their impact on high performance processing and parallel execution of Business Intelligence style queries. See also this SCN blog post.

45 Min.

If there is a slot for a 2 - 4 hour workshop, I can also deliver this as hands-on. IQ XE on Win64 or Linux64 req'd.

How to visualize Query Semantics using Open Source Graphviz

When analyzing the performance of complex queries, you may find yourself with multi table joins, e.g. generated by a BI system, coded by an out-of-reach developer or evolved through a long life cycle. A semantic query graph visualizes the topology of such a join and helps to understand the options the optimizer has at hand for an execution plan. The graph unveils possible shortcuts or extensions you can provide to enhance query performance by providing additional options to the query optimizer

I will demonstrate how to use the Open Source utility Graphviz for visualization.

This presentation is based upon ANSI Standard SQL and not restricted to a specific RDBMS implementation. The method is a generic approach to deal with the challenge of understanding and possibly enhancing the topology of a multi table join query.

Markus TheilenUsing HANA as base for playing with silosWhen watching at legacy IT landscapes there are often a lot of silos, in which data about customer and connected entities are buried. This can have a big impact on projects to digitalise processes. How about getting parts of this data out of the silos and into a platform on which the combination of data is easily done and where this data can be turned into realtime insights that are integrated in different tasks and procedures?30 - 40 minutes.

Software visualization tools - Workshop

UML is a well known technique to make diagrams of software. But it is mainly used during the development of new applications to draw overview diagrams. These are mostly used by architects, but not detailed enough for developers.

It is not well known that there are currently some companies and people working enthusiastically to change this. One project can be directly used for ABAP developments: SAP2Moose. SAP2Moose is currently used successfully in the everyday work of an ABAP developer who develops and maintains ABAP applications.

I will show in detail how SAP2Moose and Moose2Model can be used. The participants should come with own laptops and have access to an own SAP system to benefit most. But this is not mandatory. The goal is that the participants understand how they can use them in their own projects. Most of the work should therefore be done with the systems of the participants if possible.

I will also mention the commercial tool Sourcetrail. This is one of the very few commercial tools that has prices (even for the commercial version) that can be paid by developers themself (The private and trial version is free).

2 - 4 hours

Developers should know what they developed. Sometimes customers do not provide requirements of sufficient quality. It is also helpful to have some basic understanding how requirements should look like.

I also demonstrate the new open source tool This tool is a simple way to maintain requirement by the help of an Excel add in.

Paul HardyTDD Once Again

This year there has been a lot of buzz about Test Driven Development and Unit Testing, due to an Open SAP Course on the subject.

I have actually been putting my money where my big mouth is and using TDD for real on a gigantic project I am working on. I would like to share my experiences with the group, talking about the theory of TDD but more importantly the practice and what I have found to be good and bad about this.

I honestly believe this can be a huge help to all developers and will talk about some of the reasons people tend not to do this, and present counter-arguments.

Custom Code Migration to S4HANAOne of the biggest challenges for our customers during the system conversion to S/4HANA (or Suite on HANA) on-premise is the custom code adaptation. These adaptations are necessary because of the simplifications (e.g. data model changes, removal of obsolete functionality, removal of redundant components) in S/4HANA compared to the classic ERP. To minimize the efforts for our customers to adapt their code the ABAP Platform provides tools to analyze custom code based on the so-called simplification database.

This toolset is crucial for the adoption of S/4HANA on-premise.
