How to analyze the expected MPA impact on P&L before running the final process?

Summary:

How to analyze the expected Multiperiod Accounting (MPA) impact on P&L during the month without running the final accounting process?

Content (please ensure you mask any confidential information):

We would like to have visibility of the expected Multiperiod Accounting (MPA) impact on P&L throughout the month to support regular P&L reviews.

Could you please advise:

• Is there any standard Oracle report or functionality that provides visibility of the expected MPA amounts before running Create Multiperiod Accounting?
• Alternatively, is it recommended to run Create Multiperiod Accounting periodically during the month?
• If the process is run multiple times during the month, could subsequent invoice corrections or adjustments affect the reliability of the analysis or result in accounting adjustments in subsequent periods?
