To configure billing offset in Oracle Fusion Project Portfolio Management (PPM), you would typically follow these steps:

1. Access the Application: Log in to your Oracle Fusion PPM instance with the necessary privileges.

2. Navigate to Setup: From the main dashboard, navigate to the “Setup and Maintenance” work area. You may need to search for it in the global search bar.

3. Search for “Billing Offset”: In the “Setup and Maintenance” work area, use the search bar to look for “Billing Offset” or navigate through the relevant menus to find the option related to billing settings.

4. Configure Billing Offset: Once you’ve located the billing offset configuration, you can set the desired billing offset values. Typically, you would specify the number of days or months by which billing should be offset from the actual transaction or billing event. This allows you to align billing with specific business requirements or accounting practices.

5. Save Changes: After configuring the billing offset as required, make sure to save your changes.

6. Test and Monitor: It’s essential to test this configuration thoroughly to ensure it aligns with your business processes. You should also monitor billing transactions to verify that they are correctly offset according to your settings.
