About ABAP Performance Analyzer
Common ABAP performance mistakes — SELECT *, SELECT inside a loop, missing WHERE conditions on non-buffered tables — often only get caught in an ST05/SAT trace after they have already caused a production slowdown. This analyzer scans pasted ABAP code for known anti-patterns and flags them with an explanation, catching the obvious issues before code review.
How to use this tool
- Paste an ABAP method, form, or report.
- Review flagged anti-patterns: SELECT *, nested SELECT-ENDSELECT loops, missing buffering hints, and similar issues.
- Read the explanation for each flag to understand the performance impact.
- re-run the analysis after fixing the flagged code, before submitting for review.

Frequently Asked Questions
What performance issues does this tool detect?
The analyzer flags: SELECT * (read all fields), SELECT inside a LOOP (N+1 query), missing PACKAGE SIZE on large reads, hardcoded client (MANDT), nested LOOPs without index use, SORT after SELECT when ORDER BY would suffice, and access to buffered tables without the buffer.
Is this a replacement for SAP performance tools like ST05 or SAT?
No. This is a static code analysis tool that detects common anti-patterns without running the code. For real performance measurement, use ST05 (SQL Trace), SM50/SM66 (Work Process Monitor), or SAT (ABAP Trace) in your SAP system.
What is the N+1 query problem in ABAP?
The N+1 problem occurs when a SELECT runs inside a LOOP, executing one database query per loop iteration. For N records, this produces N+1 queries. The fix is to collect the key values, read all needed records in a single SELECT INTO TABLE, then process them using a sorted table or READ TABLE.
