How to Fix ABAP Memory Issues Before an Out-of-Memory Dump
“No more memory available to add rows to an internal table.” Your background job has stopped, and ST22 shows TSV_TNEW_PAGE_ALLOC_FAILED. In ECC 6.0 or SAP S/4HANA 2025, the negative reaction is to increase a heap parameter before checking whether one internal table consumed the session quota, several processes exhausted extended memory, or the program loaded […]
ABAP SELECT Performance and the Mistakes That Slow Down Your Code
Your ECC report finishes in 40 seconds. After moving to SAP S/4HANA 2025, it takes five minutes. You open ST05 and find one query reading 2.4 million rows, a SELECT SINGLE running 68,000 times, and a SELECT * returning 170 columns when the program uses only six. The problem is not SAP HANA; it is […]
ABAP Performance Interview Questions That Expose Costly Coding Mistakes

A report that ran in 38 seconds on ECC can behave very differently after an S/4HANA migration, not because HANA makes ABAP irrelevant, but because inefficient database access, repeated SQL executions, internal table processing, and poorly […]
