When trying to apply maintenance or printing the checklist for application of a product fix, an "PSPO006B Composite UNITGEN locked because maintenance not completed" error message may appear.
This message can also appear when you have entered END to generate the APPLY JOB.
A special case for when this message can appear is when a UNIT has been deleted via the checklist and somehow entries for this UNIT are still in the SHAREDPREFIX.PARMS(UGLOCK) member.
This message can also show up due to the UNITGEN1 job not being executed.
