R12.1.3 - PO accrue on receipt

We are on R12.1.3. We have PO set to accrue on receipt. We have the Project supplier invoice account generator customized as required. We want to know if we create an AP Invoice for the PO or the receipt will the Project Supplier Invoice Account Generator still get triggered? We would like the accounting on the AP Invoice Charge account to be the same what was generated as the accrual account on receipt instead of regenerating the charge account?
