Hi Bala,
I already checked the SAP note as well as the report you replied earlier.
Report SBAL_DB_DELETE will delete the application log files . I am looking to archive them first before deletion.
OSS note 195157 is a general note on Archiving BC_SBAL. It does not contain solution on archiving application logs which has keep until expiry flag enabled.
I am still checking whether such flags are enabled when we activate ILM or it is a standard SAP behaviour even without ILM
