Budget reduction during F-47

Dear Sapient

Functionality of budget reduction during down payment

Case 1

Created PO with two line item 10 & 20 with value 36,400.00 for each line item total PO value 72800

while doing transaction F-47  user enter line item 10 with total value 72800 system reduced 72800 from line item 10 but rest 36400 amount in line item 20 value revert back to respective department , generally it will be a problem to create f-47 line item  wise. Configuration done mentioned below

Budget Control System (BCS) - Availability Control - Settings for Availability Control Ledger - Define Filter Settings for Commitment/Actual Values = value type

Is there any config so that system will not ask budget during F-47,F-48  and MIRO (please guide about standard functionality of budget for down payment process with reference to purchase order multiple line item case )

Budget category - PAYMENT

Budget profile - 101

Please guide

Thanks and regards
