budgeting at the time of material procurement.

Dear friends,

Any one can guide me how to handle budgetary control to procure inventory? At the time of inventory procure system has to check for availiablity. If I'm using internal order or project the material will go into consumtion accounts. stock postion will be zero.

As per accounting standard I have to show the materials in inventory balance till I issue for consumption. Please guide me with some suitbale functionality where my procurement will raise commitment and also check for the avialiability of budget at p.o. level.

thanks and regards
