Using CSM, attempts to perform the 'apply check' on some r20 DB2 Tools' maintenance fails due to missing requisite sysmods. These missing sysmods are pre-beta ptfs.
There was a glitch in CSM (that has now been fixed) where it was incorrectly downloading 'pre-beta' ptfs.
Release : 20.0
Component : CA Database Analyzer for DB2 for z/OS
Performing a 'reject' on the r20 pre-beta ptfs, and then performing a 'delete' on them corrected the 'apply check' problem.
