How to activate the project Budget Validation to not exceed value?

Hi specialist respectable Ax consultant,

I have a case regarding the project budget, I activated (check cost against remaining budget) in the project forecast module setup

the system is doing the checking in the purchase order for the project, but it doesn’t do the checking for the value that specified in the project item forecast; also it doesn’t do any checking in the item journal.

when I made a transaction in the item journal with over limit the system allow me to post.

thanks for all
