Recently I met a situation that the customer can not delete the relevant entries from table RSDDCHNGRCHECK using the Clean-up report SAP_RSDDCHNGRCHECK_CLEANUP with option DELCNSID. Although the entries with some specific Changerun IDs can be identified in table RSDDCHNGRCHECK, the clean up did not work.
The report is provided by note 1495735 to clean up table RSDDCHNGRCHECK which was used during checking of changed records between DB and BWA after changerun.
When you run the report and select the option DELCNSID, manually entering the changerun ID in CNSID field will not work. You have to choose the CNSID from F4 list and then execute the report.
See the following screenshot.
Currently, per the coding of the program, the manual input CNSID will not get the needed internal parameter to have this report run through.
