Non-matching GL/Project module numbers allowed on requisition

Good morning,

We’ve had a few instances where a requisitioner has entered task project information on a requisition, which then inputs the default budget string for the chosen task project.

However, the requistioner has then been able to go into the account string and overwrite the project number to something which no longer matches the task project. For example, the task project entered was 033068 and was overwritten on the budget string to 033069.

This carries over to the PO and subsequently the invoice, which causes reconciliation issues between the General Ledger and Projects module.

Has anyone else had this issue, and/or does anyone know how to prevent this type of entry from being allowed?
