The processes used by Oracle Projects to generate transaction accounting dates and periods are system-defined. They are not dependent on your implementation options or profile settings. The system uses the same processes regardless of the accounting option you select. This section describes the processes that are used to generate accounting dates and periods for the various project transaction types.

Accounting Period Derivation

For all transactions, Oracle Projects sets the accounting periods to the period that includes the accounting date. PA periods are determined from the derived PA date. GL periods are determined from the derived GL date. Oracle Projects stores the PA period and GL period on cost distribution lines and revenue distribution lines.

Accounting Date and Period Derivation

As indicated below, the transaction type determines when the system generates accounting dates and periods.

• Timecard, Usage, Miscellaneous, Supplier Cost Adjustments, and Expense Report Adjustments

  Oracle Projects derives accounting dates when you run the cost distribution processes.

• Supplier Costs interfaced from Oracle Purchasing, and Supplier Costs and Expense Reports interfaced from Oracle Payables

  Oracle Projects derives the PA date for each cost distribution line when you interface the supplier costs from Oracle Purchasing and the supplier costs and expense reports from Oracle Payables.

  The system copies the GL date from the related invoice distribution line.

• Draft Revenue

  Projects derives accounting dates during the revenue generation process.

• Draft Invoices

  Both the PA Date and GL Date are derived when the invoice is generated.

• Intercompany Invoices

  Oracle Projects derives the PA date during the invoice generation process.

  The GL date is generated when you generate accounting events for the cross charge distributions.
