ABAP Debugger Guide for Functional Consultants

The debugger is a tool that can be used to execute ABAP programs by line or by section. It is the most basic tool that can be utilized to reach the root cause of any day-to-day issue faced in SAP. It not only lets you troubleshoot effectively but also helps you visualize ‘what-if’ scenarios. With this tool, you can display data objects and check the flow logic of programs.
The shared documents covers following topics:

  • Introduction to ABAP Degugger
  • Classic Debugger vs New ABAP Debugger
  • Advanced features of ABAP debugger
  • Different types of breakpoints
  • Flow of Control
  • Debugging various ABAP objects – SAP Script

How to Create Custom CDS View in SAP S/4 HANA

CDS stands for Core Data Services, which is a framework for defining and consuming data models in SAP applications. CDS views are one of the key features of CDS, which allow developers to create reusable and consistent data definitions that can be accessed by various tools and technologies.

One of the main benefits of using CDS views is that they enable a simplified and harmonized data access layer for SAP S/4 HANA, the next-generation ERP system from SAP. CDS views can leverage the power and performance of SAP HANA’s in-memory database, as well as provide a common semantic layer for reporting and analytics.

Why Custom CDS Views is used in SAP S/4 HANA ?
Sometimes the standard CDS views provided by SAP may not meet the specific business requirements or scenarios of the customers. In such cases, customers can create their own custom CDS views to extend or enhance the existing data models. Custom CDS views can be created using the ABAP Development Tools (ADT) in Eclipse, which provide a graphical editor and a code editor for defining the CDS view properties and logic.

Some of the use cases for creating custom CDS views are:

– To add additional fields or calculations to an existing CDS view
– To join or aggregate data from multiple CDS views or tables
– To filter or restrict data based on certain conditions or parameters
– To expose custom fields or annotations for consumption by other applications or tools

Custom CDS views can be consumed by various SAP technologies, such as ABAP programs, OData services, Fiori apps, Smart Business KPIs, etc. They can also be exposed to external tools or systems via SQL or REST interfaces.

Custom CDS views are an important and flexible way to tailor the data models in SAP S/4 HANA to suit the customer’s needs and preferences. They can help to optimize the performance, usability, and maintainability of the data access layer in SAP S/4 HANA.

In this document, the author illustrates how CDS views can be created with oDATA

New Developer’s Guide to IDocs in SAP

The SAP IDoc Technology is used in ALE, EDI, and 3rd Party Systems Integration scenarios. An IDoc stands for intermediate document and is simply a data container used to exchange information between any two processes that can understand the semantics of the data. IDocs are independent of the direction of data exchange. An inbound and an outbound process can use an IDoc. IDocs in the SAP system are stored in database tables. We can use transactions to view, edit, and process them. When an IDoc is generated in the system, a unique number is assigned to it via a Number Range Object. This number is unique within a client. An IDoc is created as a result of executing an Outbound ALE or EDI process whereas with an inbound ALE or EDI process, an IDoc serves as input to create an application object in SAP, like a Sales Order or PO. Using this technique avoids creating redundant IDoc types.
In this book, you will explore the architecture of an IDoc, IDoc’s definition and runtime components.

  • Basic IDoc Type
  • IDoc RUN Time Components
  • Technical Description of the IDoc Format
  • IDoc extensionsand enhancements. Why do We Need an Extended IDoc?
  • Create a new IDoc Segment using transaction WE31
  • Create a new Custom IDoc Message Type using transaction WE81
  • Create a New IDoc Assignment using transaction WE82
  • IDoc Processing and Message Control
  • Finding and Updating an IDoc Customer Exit Using SMOD

Optimizing ABAP for SAP HANA: A Three-Step Approach

ABAP is an integral part of SAP customer and partner environments, with a vast amount of business-critical data present in ABAP-based systems such as SAP Business Suite, SAP NetWeaver Business Warehouse (SAP NetWeaver BW), and on-demand offerings from SAP. These environments can benefit from the accelerated processing and analysis supported by SAP’s in-memory database technology offering, SAP HANA. Applications that use SAP HANA follow the “code to data” paradigm in which calculation logic is pushed down from the application server to the database server. The SAP HANA database then performs the calculations and sends the resulting data set back for use by an application. Operations that require high-performance access to mass data can be delegated to SAP HANA while operations used to manage and integrate business processes remain on SAP Net Weaver AS ABAP. Finally, SAP has developed a staged, three-step approach to optimizing SAP NetWeaver AS ABAP for SAP HANA that will help customers and partners gradually integrate in-memory innovation without risking their existing implementations.
After reading this document, you will be able to:

  • Know about the basics of SAP ABAP and SAP HANA
  • Optimization techniques for SAP HANA Database
  • How to access SAP HANA through ABAP applications
  • Basics for migrating ABAP code to SAP HANA
  • Different performance and functional checks
  • About different performance analyzer tools
