Check the project and phase status in BQE Core
If the project or phase status is Completed, you will not be able to sync additional expenses to the project or phase.
Solution: Work with the Project Manager on the project to determine if the vendor bill should still post to the BQE Core phase. If yes, navigate to the phase in BQE Core, change the status to Active, run sync, and return BQE Core status to Completed. If no, change the project and phase on the vendor bill in BILL, and run sync.
