* RDO definitions (conceptual)
CEDA DEFINE PROCESS(ORDER-BP) GROUP(BTS-GRP)
CEDA DEFINE ACTIVITY(PROCESS-ORDER) PROGRAM(ORDPROC) GROUP(BTS-GRP)
CEDA INSTALL GROUP(BTS-GRP)

Compensation Pattern

Ensure each mutating activity has a compensating counterpart for rollback of prior steps.

Error Handling

• NOTFND on INQUIRE/CONNECT: verify process instance exists and IDs match.
• INVREQ: definition mismatch, missing attributes, or invalid state transitions.

Monitoring

Use CICS Explorer BTS views to observe processes, activities, and container contents in real time.
