We have a program that calls GSVCMEI in CICS to set an umbrella field and also sets the userid and term fields in the transaction record. We also have a batch process that will set some of the transaction record fields off with these commands: . .COMMAND=(CICSSET CONFIG TRANSACTION-DATA-RSCEMGR NO) When we upgraded to Sysview V15.0 from 14.2 we noticed that the call to set the fields in the transaction record began getting a 24 return code. If we leave TRANSACTION-DATA-RSCEMGR set to yes then the call works. When we were under V14.2 the calls always worked. Has something changed in V15.0 that requires TRANSACTION-DATA-RSCEMGR to be yes in order to set the fields in the transaction record?
