Discrepancies between Budcon report and FMAVCR02

Hi.

When I check a fund using transaction FMAVCR02, I see the amount available, which is X. The client does not have permission to run this transaction, so they use the budcon report to check the availability, and the amount available is much bigger, that's why they thought they could block the fund.

FMAVCR02

-Budget addresses

-Introduce fund number

-Amount available = X

FMRP_RW_BUDCON

-Introduce fund number

-Introduce fund center N/A in or vaue field

-Execute report and select Commitment ceiling consumption, and the amount available for my fund = 52X

Why there are discrepancies between these two reports? As far as I understand, quantities in both reports should be the same, right?

I hope you can help me.

Thank you
