An ABAP tool to get ABAP source codes line number

You can use this tool ( an ABAP report ) to get the line number of your ABAP source code.

How to use this tool

Just specify the criteria based on which the source code will be scanned and line number will be calculated.

CDS view source code count tool Part-12

The Continues Blog, For development complexity and draft effort estimation I need a tool to calculate the total line number of the CDS views belonging to a given package.

ABAP Nested Loop Performance Test

During an ABAP performance discussion, we decided to run tests to decide on the best method for nested loops. The example was to have an outer loop of BKPF and an inner loop of BSEG.

Nesting two raw loops gives the worst performance in all cases; therefore I have left it out.

In our initial test using the source code shared below; here are the methods ordered by better performance:

How to create ABAP CDS View with enabling derivation of the value for parameters

There have been dozens of blogs online for walking through developers on how to create ABAP CDS view with parameters in ABAP for HANA, however, one major issue still exists is that although input parameters can restrict or filter the data from CDS views, the limitation of the value input for a parameter to filter out more specific data range is significant.

Here the author presents you a way to enable derivation of the value for parameters to tackle similar problems in your future development using the example shown below.

Regarding cookie manipulation in CL_HTTP_CLIENT to avoid CSRF token validation failure issue

Recently I meet with this cookie issue so I document it as a blog in case any other guys might meet with the same problem.

I am trying to create some Opportunity transaction data by consuming OData service via CL_HTTP_CLIENT. Since this is a update operation which needs to be finished by HTTP POST, so a CSRF token is needed in this HTTP post. Let’s first have a look what is a typical scenario running in Chrome extension postman:

Old New ABAP Editor

Introduction

If you develop now UI for SAP, you use Web IDE. If you are doing backend and ABAP, you use ABAP in Eclipse. But sometimes you still need to come back to SAP GUI and ABAP Workbench and use the “New” ABAP Editor.

ABAP Group Operations in Internal Tables

Today, we will be inspecting some cool grouping techniques introduced in ABAP 7.40.

First, let’s get familiar with our context. We will read the table T001K, where BWKEY (valuation area) is the table key, but BUKRS (company code) is repeated multiple times in various lines. Let’s start off by reading this table.

Converting Function Module Exceptions to Exception Classes

Although function modules belong to the era of procedural programming, we all need to use them from time to time. While most BAPI’s usually return error messages in a clean internal table format, many other function modules return classical exceptions.

If you are calling a function within a class method, you might have a hard time converting those classical exceptions to class based exceptions – meaning exception classes.
