SAP: Basic Approach to Tackle with ABAP Performance Problems (by Code Inspector & Transaction ST12)
This video shows you how to check, analyze and improve the source code of ABAP program.
The contents are followings.
1) Proactively check the potential risk of performance problems
2) Precisely analyze the performance bottleneck
3) Improve the source code and re-check it
The step 1 is accomplished by the tool Code Inspector.
Code Inspector is the tool of SAP BASIS, so it is already existing in your system and it is not necessary to install additional softwares and execute settings.
The step 2 is accomplished by the transaction ST12.
The transaction ST12 belongs to the software component ST-A/PI, and this component is normally installed to your system as a default, so you don’t need additional preparations to use it in many cases.
Regarding the performance problem, it is focusing on SELECT statement in LOOP in this video.
Therefore checking/improving the source code is only about SELECT in LOOP problem.
However the approach explained in this video can be used for any other ABAP performance problems.
So you would be able to understand how to tackle with the issue of ABAP program performance in general through this video.
I hope this video will be the good reference for your ABAP performance tuning.
