Deletion of requests from Write optimized DSO

Hi all,

Tried using this RSSM_DELETE_WO_DSO_REQUESTS to delete requests more than 60 days, via process chain.

But this is not removing all requests more than 60 days. Quite a few are not getting deleted and even on second run of this program, deletes one request at a time. Not sure why this behaves this way.

Any other alternative as Deletion of WDSO (Write-optimized DataStore object) Load requests and active table data without deleting it from target

This also seems to work...?

Also, how should I ensure uniformity of timelines w.r.to PSA and changelog of this DSO flow? PSA 15 days and changelog 90 days retain is fine? Want to ensure no data comes again thats deleted in WDSO
