Why are revenue amounts being reported on the financial project plan even after I disabled the option to calculate revenue amounts?

When you select the Enable revenue for project plan check box and then the appropriate Revenue Calculation Method under the Plan Settings tab on the Create Project Plan Type or Edit Project Plan Type page, the revenue amounts are calculated and stored in the database.

Now, you clear the Enable revenue for project plan check box and then perform reporting using a REST service or Oracle Transactional Business Intelligence, the revenue amounts still get reported because the application picks the calculated revenue amounts that are stored in the database and includes them in the reports.
