PECI Merge Files Integration Fails: "The Task Submitted Is Not Authorized" (ISU Domain Gap)
What it means
A PECI integration calling the "PECI - Merge Files" integration through a business process completes with errors because the ISU driving it lacks security access to the objects the merge step touches. Removing the ISU and running as an admin only "fixes" it because the admin has broader access, not because the integration is misconfigured.
Troubleshooting
- Reproduce the failure with the ISU still attached, and confirm it only happens with the ISU in place (not as an admin). That isolates the cause to the ISU's security group, not the integration definition.
- Check the ISU's security group against the Integration Event, Integration Process, and Integration Build domains. A "Merge Files" step invoked via business process needs more than the segment-based security groups (Financial, Position, and Award Segment) it may already have.
- List every domain the merge step and its underlying business process touch, not just the obvious Integration Permissions ones, since PECI's merge step can call object types the ISU's existing grants don't cover.
- Activate pending security policy changes after adding the missing domains, then re-run with the ISU restored.
Add the ISU's security group to the Integration Event, Integration Process, and Integration Build domains, activate pending changes, and re-run with the ISU attached.
When building a PECI integration that invokes Merge Files through a business process, grant its ISU security group Integration Event/Process/Build domain access up front as part of setup, rather than discovering the gap only after a "completed with errors" run.
