   Fresh Install: New customers who install Oracle Applications for the first time and enable MRC.

Note: For Oracle subledger applications that support MRC, you must enable MRC before entering any transactions in the subledgers. There is no such restriction for General Ledger.

   Upgrade Scenario 1: Existing customers who upgrade from an earlier release of Oracle Applications, then enable MRC.

For Oracle subledger applications that support MRC, you must enable MRC in:

• A new set of books or

• A new operating unit in an existing set of books

before entering any transactions in the subledgers. There is no such restriction for General Ledger.

   Upgrade Scenario 2: Existing customers who upgrade from an earlier release of Oracle Applications, then enable MRC for an existing set of books or operating unit when there are open transactions in subledgers that support MRC.

Note: An open transaction is a subledger transaction whose accounting lifecycle has not been completed. For example, a receivables invoice for which you have not received payment from the customer, a payables invoice which you have not paid, or a project that has an open status.

Following the patch, a planned maintenance release for MRC will support a third upgrade scenario:

   Upgrade Scenario 3: Existing customers who upgrade from an earlier release of Oracle Applications, enable MRC, and want to convert historical transaction amounts in their subledgers to their reporting currencies.

Notes

   For both Fresh Install and Upgrade Scenario 1, if you enter transactions in a subledger before enabling MRC, there will be open transactions when MRC is enabled. Any subsequent entries related to the open transactions (e.g., credit memos, receipts, payments, or project expenditure adjustments) that occur after MRC is enabled will not be converted to reporting currencies and may cause an error condition.

To avoid this situation, you must install the planned patch when it becomes available, then convert the open transactions to your reporting currencies.

   If you are an existing customer upgrading from an earlier release of Oracle Applications and you have no open transactions in subledgers that support MRC, you can enable MRC for those subledgers without creating a new set of books or operating unit.

Warning: Do not reopen closed transactions if you have enabled MRC without creating a new set of books or operating unit.
