Please Read before Posting in the ABAP Testing and Troubleshooting Space!

Community members are happy to help you with your troubleshooting and performance tuning problems, but before posting, please make sure you have done some analysis to find where the problem in your program lies. Two of the more helpful transactions are the performance analysis (transaction ST05) and the runtime analysis (transaction SE30). If you are unsure about how these transactions work, here are a couple of blogs (both by Siegfried Boes) to get you started:

The SQL Trace (ST05) – Quick and Easy
The ABAP Runtime Trace (SE30) –  Quick and Easy

and by Hermann Gahm:


Single Transaction Analysis (ST12) – Getting Started

Explaining the SQL Explain Plan

Transaction SAT is replacing SE30 from Netweaver 7.0 EhP2. An excellent introduction by Olga Dolinskaja can be found here:

Next Generation ABAP Runtime Analysis (SAT) – Introduction


Also, code inspector can do some static performance checks before your code hits large databases, Randolf Eilenberger wrote a series of blogs about it:


Code Inspector’s Performance Checks

Look out for additional publications by these authors!

Additionally – the following questions have been asked and answered many times before, so please do not ask them again:

Which is better: A JOIN or FOR ALL ENTRIES? -> For All Entries is NOT better than INNER JOIN in most cases

Which is better SELECT/ENDSELECT or SELECT INTO TABLE? -> SELECT INTO TABLE

Which is better MOVE-CORRESPONDING or MOVE individual fields? -> Using MOVE-CORRESPONDING – Myth to Meaningful

Tell me about performance tuning? -> tcode for performance tuning and usefull links and material for pt

Which is better MOVE or = ? -> Move and “=” Difference

Which is better SELECT SINGLE or SELECT UP TO 1 ROWS? -> Select Single Vs Select upto 1 row
