PECI Worker Skipped: Unprocessed Prior Event
The error Worker [ID]: change not processed. A prior effective-dated event for this worker is pending in an unconfirmed state.
What does "PECI Worker Skipped: Unprocessed Prior Event" mean in Workday PECI?
PECI builds per-worker deltas in effective-date order. This worker has an earlier event still pending - an in-progress business process, unconfirmed payroll input, or an unacknowledged previous extract - so the connector won't emit the newer change until the earlier one resolves.
Quick fix
Complete or cancel the blocking event (or process the missing acknowledgment), then re-run the extract. The held changes will emit in order.
Permanent fix
Monitor BP queues for events older than the payroll cutoff. Enforce the acknowledgment flow with the payroll vendor. Add a pre-payroll-deadline report of workers with in-progress events so blockers get cleared before the extract runs.
Troubleshooting
- Open the worker's event history and look for in-progress or unprocessed events before the stuck change's effective date.
- Check whether downstream payroll acknowledged the previous PECI file - a missing ACK can hold the worker in a pending state.
- Review the PECI run history for this worker across the last few extracts to find where the chain stalled.
- Confirm the business process that created the earlier event is actually completed, not sitting on an approval step.
