Prepayments Matched to Projects Purchase Orders also appear as commitments

Hi,

We normally give prepayments to our suppliers in order they can deliver our products related to a Project Purchase Order.

For example, I have a purchase order with an amount of $1,000,000.00 USD. So, our supplier requires a 10% prepayment in order to start working on the delivery of material. In Oracle Payables we enter a prepayment invoice for the 10% of the total purchase order, in this case: $100,000.00. This prepayment is matched against the PO.

What we expect to see as commitment in Oracle Project Costing within the PSI form is the original commitment that comes from the purchase order, in this case $1,000,000.00 . But the system also considers the prepayment amount as commitment, in this case the commitment is wrong as the prepayment was matched against the PO  so the commitment amount would remain the same $1,000,000.00
