Dear Farzana
Just to cross check, please see if your budget document going through workflow? If yes, then check and post the document via FR70.
Did you see the consumed budget via FMAVCR01. Consumable amount should be your budgeted figure and consumed amount is the budget you have consumed. Expand the levels at commitment item level and double click on the consumed part and see the document details.
Hopefully you may get the answer here.
