Budget exceed issue while doing MIGO

Dear All,

Budget exceed issue is coming while doing MIGO.

WBS Budget uploaded: 532,000 (INR)

Commitments: 417,530.07 (INR)

Available: 114,470 (INR)

PO vaues:

Gross Price(PBXX): 9,297 (CHF)

Customs: 1,481.25

CVD-NO MODVAT: 1,383.22

ECS on CVD: 27.66

Sec ECES ON CVD: 13.83

ECS on Customs: 58.12

HECS on Customs: 29.06

IN ADC 752.08

Actual Price: 13,862.22 (CHF)

No Taxes.

As per exchange rate shown in the PO which is 30.12 the commitment amount is same as actual price.

Now while doing MIGO the error is coming as "WBS element, budget for fiscal year 2010 was exceeded by 16,014.08 INR"

Message no. BP604

What could be the reason.

Thanks in advance

Shubham
