AVC & Residual Budget Error - Urgent..

Dear SAPs...

I am finding a peculiar error in PSM.

Uploaded budget is      1000.

Invoiced is                    200

Commitment is            100

Residual shows as       700          

But in FMRP_RW_BUDCON, it give 1000 as consumed and no available budget... Actually, it should be 300.

When i drill down the report,,i am getting Line items only for 300, not for 1000.!!!!

i checked with all the reports and in all report it gives 300 as consumed and committed... But i am unable to use 700 residual..

Kindly share some inputs and views..

Regards
