GL : Budgets

Dear All,

 

We have implanted and using from past 3 years R12.1.1 (AP,AR,GL,PO,CM,FA,PJC).

Now from upcoming latest Year we want use budgets & budget controls at PO level and invoices Level.

For Projects we will be going to give budgets with in the PJC module.

We have 13 periods (12 + 1 adjusting).

For past years we have not implemented and we are using accounting method is Encumbrance accrual.

Please give your thoughts while implanting budgets and budgets controls what steps have to take attention??

What critical issues we will have because budgets not rooted for past years (up to 2012)???
