R12.2.4 - SLA on the PO Charge Account override during receipt

We are on R12.2.4. We have Project related POs. These POs are received and cost is transferred to Project. Subsequently this cost is capitalized.

We plan to use SLA on the receipt and override the debit PO Charge Account. For e.g. if PO Charge Account is X we will override it to Y  using SLA on the accounting generated during receiving process.

We want to know which CIP debit account will be transferred to Projects  X or Y? We assume this CIP debit account will subsequently be cleared upon capitalization in FA. (DR Asset Cost Account, Cr CIP).
