Options for importing purchasing receipt accruals into PPM(Accrue at Period End & Accrue at Receipt

Summary:

We have project-based POs with Expense destination which are accrued at Period End. We also have project-based POs with Inventory destination which are accrued at receipt.

Can someone please explain how the receipt accrual entries are imported into Project Costing for these 2 scenarios (Accrue at Period End & Accrue at Receipt)? We are unclear about how these entries are imported/reflected in project cost after those transactions are processed thru Cost Management module.

If there's no standard functionality for processing one/both of these receipt accrual transactions into PPM, what are the workaround options for recording those accruals in PPM?
