How to Integrate multi-period accounting in Payables to Purchasing and Projects?

Hi All,

Our company is a project driven company. When we create Purchase orders that contains Project, Organization, Expenditure Type, Task and Expenditure Date information. Invoices for these are created by matching to purchase orders.We wanted to record expense of such pre‐paid invoice lines over a given period. Also, we wanted the information to flow into projects in the same fashion as information flows into GL from AP. We reconcile the Projects amounts by expenditure type to GL account balances. I'm looking for some type of documentation whoever is already done. Please share a document if available. Thanks
