Summary :
In English: Tables with the prefix "QCM" exist in the database without documentation in the ABAP Dictionary. These tables temporarily store data during conversion processes and are deleted for each relevant table before conversion. However, they are not automatically removed afterward, wasting database resources. From Release 3.0D, QCM tables are deleted post successful conversion, except in cases involving duplicate key inserts. Pre-Release 3.0D, these tables must be manually deleted after verifying consistency using database utilities like SE16. If consistent, tools such as 'sqlplus' or 'sqldba' can be used for deletion. Post-Release 3.0D, SE14 simplifies this process.
Key words :
'manager->tools-> query tool', select 'extras->invalid temp, call transaction se14, unnecessary database resources, conversion program determined, conversion procedure termination, affected original table, delete qcm tables, original table, transaction se16
