Question 270
A synchronous custom API invokes a helper that reenters a registered Update step and generates duplicate audit rows. Which Power Platform extension or architecture change BEST addresses the core requirement?
Explanation
Correct Answer
Design plug-in logic that avoids self-triggering Update loops and guard against repeated processing with idempotent business conditions. This choice implements the controlling platform requirement rather than masking the symptom. Blocking all depth greater than one can suppress legitimate nested operations; fix the causative loop and design safe checks. Verify the change using: Inspect execution depth, parent context, plugin registration stages, update attributes and processing marker.
Incorrect Answers
Register a signed plug-in assembly, target message, step mode/stage and image configuration with supported tooling and deploy it in a solution. That action addresses Plug-in Registration Tool and signed assembly deployment instead. Publishing a DLL without a registered step does not automatically attach code to Dataverse messages. For this case, the targeted action is: Design plug-in logic that avoids self-triggering Update loops and guard against repeated processing with idempotent business conditions.
Use PreValidation for early validation outside the main database transaction where appropriate and throw InvalidPluginExecutionException for unsupported operations. That action addresses Dataverse PreValidation plug-in and aborting operations instead. PreValidation is often outside the main transaction but may run within an existing parent transaction; verify actual context. For this case, the targeted action is: Design plug-in logic that avoids self-triggering Update loops and guard against repeated processing with idempotent business conditions.
For 429 or service-protection responses use documented Retry-After and bounded exponential backoff with idempotent processing. That action addresses Dataverse API service-protection throttle retry instead. Rapid blind retries can amplify platform throttling; not every 4xx error is transient. For this case, the targeted action is: Design plug-in logic that avoids self-triggering Update loops and guard against repeated processing with idempotent business conditions.
