Followed process detailed on KM: HOWTO79488; however, the targeted custom filter for the 'Windows Patch Remediation Settings' policy is being removed.
ITMS & Patch Management 7.1 SP1, SP2 & MP1.x
Found the clean up process clears the custom filter from the policy if it is not 'accessed' within 7 days. This is to prevent target membership bloating within the Symantec_CMDB database.
However the targets for the Windows Patch Remediation Settings policy are stored in the "State" column of the the policy, in the ITEM table; as a result tracking its usage does not seem to occur.
Advisory: this Target will be cleared if anything other than the default: 'Windows Computers with Software Update Plug-in Installed Target'
This issue is resolved in ITMS 7.5.
