Sorting with any/multiple fields in table maintenance

Below are the steps to be followed if you want to provide sorting in the table maintenance generator.

  • Please go through the below blog to add a new custom button in TMG screen
  • Then create one custom FM with following logic that will popup the dialog box for the user to select the columns of table control in SM30.
  • This FM should have view name of type DD02L–TABNAME as importing parameter and exporting parameter of type ABAP_SORTORDER_TAB  that contains the field names to be sorted.

How to extend an ABAP Managed Database Procedures using AMDP BADI’s

With ABAP 7.4 SP08, the modification-free enhancement of AMDPs is now possible using so-called AMDP BAdIs. The AMDP BAdIs transmit the effect of the switches from the Switch Framework to the implementation of database procedures in the current database. It allows the definition of a clear contract between extension provider and extension consumer (aka implementer) through a dedicated interface. AMDP BAdIs are created in Enhancement Spots in the transaction SE20 and are later called within an AMDP implementation similarly to other AMDPs.

Remote Code Analysis in ATC – Technical Setup step by step

Technical Requirements

To use Remote Code Analysis in ABAP Test Cockpit (ATC) you need to install and configure one ATC central check system SAP_BASIS = 7.51. The systems, which you want to check in your landscape, must be on SAP_BASIS 7.00, 7.01, 7.02, 7.31, 740 or 7.50 releases.

The RFC destinations for all checked systems must be provided in the ATC central check system and RFC-stubs must be implemented in all checked systems (SAP Notes 2270689 and 2190065).You would also need authorizations for administrative and quality assurance activities. See Authorizations for the ABAP Test Cockpit.

About “classic” and Standard ABAP-Debugger (“Display List”-Option)

For a few years, I have been using the “new” ABAP-Debugger, and I’m quite happy with it (learning something new every other time, e.g. cool features for exploring memory usage or down- and uploading data (but only up to 500000 Lines) from/into internal tables).

Only recently I was missing a feature I knew I had used in the past: “Display List”.

Sorting Columns Dynamically in a Table Control

This is about dynamically sorting the contents of a column in a table maintenance generator and in turn within a table control.

1 : Consider a table ZTESTL with columns for Material , Language & Material Description.

Step-by-Step procedure for creation, execution and storing of ABAP Managed Database Procedures in HANA

ABAP Managed Database Procedure

Database Procedures are stored and executed in the Database. We can create and execute database procedures in HANA database through ABAP using AMDP Class and AMDP Method called ABAP Managed Database Procedures. SQL SCRIPT is the language for creating stored procedures in HANA. Main benefit of using SQL Script is to allow the execution of complex calculations inside HANA database. The language is varies from one database system to another.The ABAP Managed Database procedures should be created using ABAP Development Tools (Eclipse or HANA Studio).

Remote Code Analysis in ATC – One central check system for multiple systems on various releases

ATC Introduction

For those of you, who are using Code Inspector (SCI) and are not familiar with ABAP Test Cockpit (ATC) yet, it is SAP’s central quality assurance infrastructure for static functional, performance and security code checks, which bundles together the well-known and widely used quality tools like syntax check, SLIN, ABAP Unit, security checks and is extensible for your custom checks. ATC reuses Code Inspector checks and significantly improves the code quality by offering the uniform quality criteria for the whole development landscape and establishing new quality assurance processes (quality gates, exemptions, mass regression tests) to minimize errors in productive systems. Beyond this ATC is the toolset of choice to achieve the smooth migration of ABAP code to SAP HANA and SAP S/4HANA by means of special SAP HANA and SAP S/4HANA checks.

Layer-Aware Debugging in NW 7.0 EHP2

Software Layer-Aware Debugging (SLAD) in NetWeaver 7.0 EHP2

The Problem…

Have you ever had this problem?  You need to analyze a bug, or you want to find out how an application works. And you don’t know where exactly to set a breakpoint. So you start the ABAP Debugger and start stepping through the code.

ABAP TDD in NetWeaver 7.0 EHP2

I showed what the Test-Driven Development cycle might look like in the ABAP Workbench (SE80) in NetWeaver Release 7.01. Unfortunately, the TDD experience in that Release was marred by a hurdle right at the start of the process of implementing an ABAP class. That hurdle has been removed, and there are three other important improvements to ABAP Unit.

With NetWeaver 7.0 EHP2 (Release 7.02), the process has become a little bit more graceful. This weblog reviews what ABAP TDD looks like in practice in Release 7.02.  (Look for even more improvements in support for ABAP TDD in the Customer Engagement: Evaluation of the Pilot Version of ABAP in Eclipse.)

Customer Engagement: Evaluation of the Pilot Version of ABAP in Eclipse

Why ABAP in Eclipse?

The idea of offering an ABAP development environment in Eclipse may surprise some experienced ABAP developers, since the classical ABAP Workbench since years has proved itself as an integrated, comprehensive business development environment with a rich toolset for development, testing, troubleshooting and support running on a powerful server with a sophisticated, robust life cycle management. On the other hand Eclipse has established itself in the world as a state-of-the-art open development platform with the powerful UI capabilities, which are second to none and nowadays many developers are fascinated by its usability, productivity and flexibility.

ABAP Debugger Scripting: Advanced

It’s easy to write your own ABAP Debugger Scripts in NetWeaver 7.0 EHP2, either for ad hoc use directly in the debugger or for re-use by you or your colleagues.  An ABAP Debugger Script is an ABAP Objects program that runs under the control of the debugger.  The script automates your activities in the debugger by calling the services offered by the ABAP Debugger. In this weblog, we show you how to write a script, whereby the most important topic is how to use the Script Wizard to call the services of the ABAP Debugger from a debugger script.  We also demonstrate some sample scripts for tracing, creating individualized breakpoints, and extracting data for display from complex data objects.

ABAP Debugger Scripting: Basics

Now that NetWeaver 7.0 EHP2 is available as a Mini-Basis System, we can tell you about some of its new features.

One of the coolest of these new features for problem analysis is ABAP scripting in the New ABAP Debugger. In this weblog, we explain what this feature is for, what the script workplace looks like, and how to run a couple of first scripts to whet your appetite.  You’ll see how to do a complete trace of executed statements from the script overview, and how to see where particular statements occur in your (executed) code.

Unit testing mockup loader for ABAP

The tool is created to simplify data preparation/loading for SAP ABAP unit tests. In one of our projects we had to prepare much tables data for unit tests. For example, a set of content from BKPF, BSEG, BSET tables (FI document). The output to be validated is also often a table or a complex structure.

Data loader

Hard-coding all of that data was not an option – too much to code, difficult to maintain and terrible code readability. So we decided to write a tool which would get the data from TAB delimited .txt files, which, in turn, would be prepared in Excel in a convenient way. Certain objectives were set:

ABAP on HANA – Steps to call a CDS view from another CDS View

Core Data Services (CDS) :

CDS is an infrastructure layer for defining semantically rich data models, which are represented as CDS views.

A CDS view is used to define the structure of an SQL view and represents a projection onto one or several ABAP Dictionary tables or ABAP Dictionary views.

This blog shows how to call a CDS view from another CDS view.

ABAP on HANA – Step by step procedure to create a CDS view using input parameters to display multiple records.

This blog shows how to display multiple records by using input PARAMETERS keyword, As there is no provision to use ABAP keyword SELECT-OPTIONS which display multiple records in CDS View.

1. Go to Dictionary => ABAP DDL Sources => New Data Definition
