Trying to open, via a MacKinney Batch to CICS job, a Datacom URT on a CICS region where there is no PPT for that URT program.
The OPEN obviously fails, but the DB Return Code passed by the MacKinney error message is blank:
DBLC OPEN=086 <ERR 06/16/22 00:36:04 MBCRXDPL 2.1 USZAPK4
MBCE137-COMMAND DBLC OPEN=086 WAS UNSUCCESSFUL RC( ) 06/16/22 00:36:04 MBCRXDPL 2.1 USZAPK4
DBLC OPEN=086 <FLSH 06/16/22 00:36:04 MBCRZIN 2.1 USZAPK4
MacKinney support states that they are simply displaying the Return Code returned by Datacom.
Release : 15.1
Component : DATACOM CICS SERVICES
When a URT has no PPT entry, the error message (DC00202I URT nnnn-mmmm HAVE NO CSD ENTRIES) is returned by Datacom CICS Services before Datacom could issue the OPEN, so there is no Datacom Return Code.
