The APPLID and TRANID indicating the CICS® region and transaction, under which the failed application program was running, where the error actually occurred.
This can be different from the PutApplid if an error occurred in a DPL or WebSphere® MQ server adapter that was not running in the same region as the controlling adapter Navigator (for example, due to Workload balancing). The DPL and WebSphere MQ server adapters do not do PUTs to the CICS Service Flow Runtime Error queue. Instead, they return control to the adapter Navigator indicating the error. The Navigator subsequently performs the PUT to the error queue.
