PA Budgetary Control

I'm controlling the PA budget with any GL integration, so I want to separate the project's budgets.

But when I create a purchase order, this one go through a project validation (it is ok) and a GL validation (this is wrong) so when the account does not have assigned budget in GL my budgetary control (purchase order) ends with exception, and the results that I have read, tells me that I do not have budget for that account. It is wrong because my budgetary control is seting up just for project control.

Maybe there is a profile that integrated both of them and I have pushed it on casually.
