Hi,
I review this issue in standard enviroment, This is the scenary:
1. Create a new Proyect of T&M
2. Setup Budget and forcast Control

3. Aprobe a new Project Budget with $500 in a Category Project of Item, and pass to In progress status
4. Insert a new Item Requirements (Doesnt matters if is a service or product Item)
5. Create A Purchese Orden from Item requirements form with this value $500
6. Confirm de Purchase Order. Next one, Recibe and consume the Purchase order
7. Post the invoice of the Purchase order, and you have the issue: The entry for category ProjItem on project 000236 cannot be submitted because it would cause the cost budget to be exceeded by 500.00.

Please, anybody knows what is the solution please.
Thank you,
César
