DFS3946I PST NOT FORMATTED -- REQUESTED PST IS NOT A SYSTEM PST

Explanation
 The requested PST was not an active system PST.
An invalid SYSPST request (the PST might be a DPST instead) caused
this condition.

System action
 The SYSPST option formatter terminates the current
request and continues with the next request.

User response
 Ensure that all SYSPST formatting requests are
valid. For assistance, see the IMS system
programmer.
