C_CPI Integration Suite Development Practice Question
An integration developer is troubleshooting an integration flow that uses a Multicast step to send the same message to two branches. One branch writes to an SFTP server and the other branch calls a SOAP service. The developer notices that when the SOAP branch fails, the SFTP branch also appears to roll back. What is the most likely cause?
⚠ Common exam trap
The trap here is attributing cross-branch rollback to parallel processing or a multicast flag, when the real driver is the shared transaction boundary of the message exchange.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The integration flow uses a single transaction boundary across the multicast, so a failure in the SOAP branch causes the entire message exchange, including the SFTP write, to be rolled back.
The symptom is that a successfully executed branch is undone because another branch failed. That indicates the branches are inside the same transactional scope, so an exception in the SOAP call triggers a rollback of the whole exchange, including the SFTP write. Isolating branches or handling errors locally prevents cross-branch rollback.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Multicast step was configured with Parallel Processing and the branches share the same message exchange, so an exception in one branch causes the whole exchange to fail.
Why it's wrong here
Parallel Processing changes execution order and thread usage but does not by itself make one branch's failure roll back the other. The branches still operate on separate copies of the message. The observed rollback behavior points to a different configuration issue, such as error handling or transaction scope, not merely to parallel execution.
- ✗
The SFTP receiver adapter is configured with `Use Temporary File`, so the file is written only after the SOAP branch completes successfully.
Why it's wrong here
`Use Temporary File` affects how the SFTP adapter writes a file, typically renaming a temporary file after a successful write. It does not coordinate with a separate SOAP branch or cause rollback based on that branch's outcome. The described cross-branch rollback is a transaction and error-handling concern, not an SFTP adapter file-writing option.
- ✓
The integration flow uses a single transaction boundary across the multicast, so a failure in the SOAP branch causes the entire message exchange, including the SFTP write, to be rolled back.
Why this is correct
When steps participate in the same transaction and a later step fails, the runtime can roll back the whole exchange, undoing earlier side effects such as the SFTP write. Separating branches into their own transaction boundaries or handling errors locally prevents one branch's failure from rolling back the other. This matches the observed behavior.
- ✗
The Multicast step is missing the `Stop on Exception` setting, so the SFTP branch is aborted when the SOAP branch throws an error.
Why it's wrong here
`Stop on Exception` controls whether the multicast stops other branches when an exception occurs. If it were enabled, the SFTP branch could be skipped, but the symptom described is rollback of an already-executed branch, not skipping. The setting is relevant to branch continuation, not to transactional rollback of a completed SFTP write.
