Prepayment Invoice Mechanism in Project Budget Consumption

Summary:

Hi

I have project budget balance 1200. I create PO with amount 800. Project budget balance will be 400. The supplier request us to pay first 50%, so I create prepayment invoice matched to PO with amount 50% * 800 = 400. The PO charge account and Prepayment Invoice charge account is different, because the company policy. How much project budget available balance left?

My expectation is project budget balance still 400. Because we pay 400 not create new budget consumption, but using budget consumed by PO. But in my instance, the project budget balance is consumed again by prepayment invoice.

Thank you

Aji
