An EXEC CICS® RUN ACQPROCESS has failed in the DPL Stub program (DFHMADPL) when attempting to run a process in the CICS business transaction services system with the CICS Service Flow Runtime Navigation Manager as it's root activity. The process is requested to run ASYNCHRONOUS if the request definition indicates asynchronous mode and SYNCHRONOUS if the request definition indicates synchronous mode.
The request type is specified on your type R record PARM01 for the failed request name in the Properties file update JCL. You can dump the CICS Service Flow Runtime Properties file (DFHMAMPF) using job DFHMAMPD. The request name is found in the DFHMAH header structure of the request message at execution time.
Dump the error log (DFHMAERF) to determine the problem. Check that the request was in synchronous mode, and that the transaction and program are available and not defined as remote. There may have been a problem with the repository file - check the CICS log.
