If your site uses LU assignment processing for non-unique UserIDs, and if the process terminates abnormally due to a CICS® Service Flow Runtime system error or an incorrectly modeled flow, this can result in LUs remaining assigned.
The CICS Service Flow Runtime / BTS process that was initiated to execute that modeled flow will, upon issuing a reply to the service requestor, complete.
Under the complete state there will be no CICS Service Flow Runtime / BTS process container information available for subsequent use to locate, use and / or logoff assigned LUs.
For this reason, the LUs that were assigned will have their sessions (FEPI conversations) terminated and assignment deleted before the CICS Service Flow Runtime / BTS process is complete, successfully executed or not.
The CICS Service Flow Runtime DPL Stub program (DFHMADPL), will cleanup / process LUs assigned in this manner before issuing the reply of an executed process to the service requestor.
The CICS Service Flow Runtime / BTS process will then be completed.
