The DISCARD PROCESSTYPE command removes a CICS® business transaction services (BTS) PROCESSTYPE definition
from the local CICS region.
Notes:
Only disabled process-types can be discarded.
If you are using BTS in a single CICS region, you can use the DISCARD
PROCESSTYPE command to remove process-types. However, if you are using BTS
in a sysplex, it is strongly recommended that you use CPSM to remove them.
If you don’t use CPSM, problems could arise if Scheduler Services routes
to this region work that requires a discarded definition.
