How to fix: Duplicate submission detected for project '...'.

What happened?

The portal has detected that a certified payroll report for this project and week has already been submitted. Duplicate submissions are rejected to prevent data conflicts — even if the original submission had errors that you're trying to correct.

The Zero-Tolerance Solution

XMLExpress tracks submission history per project and week, warning you before generating a duplicate. If you need to amend a previous submission, we guide you through the correction workflow.
