Some FCC applications have an issue where data loads done with an admin ID are not calculating correctly after the data load. What is happening is that the data status isn't correctly being set to impacted and so the subsequent calculation/consolidation doesn't bring forward opening balances, calculate movement, etc.
The workaround for this is simply to do the data loads with a non-admin ID. Or do something that impacts all status, like a database refresh.
Sources tell me that Oracle is planning (safe harbor statement applies) to do an off-cycle update to the test environments this week, probably on Jan 14. Once that happens, admins can test the fix in the test environment and then file an SR to request that their production environment gets an early update. Both the test and production updates would happen during the daily maintenance cycle, which can either be run on the normal schedule or on-demand using EPM Automate. Or, if the early update is not desired, then continue with either workaround until the regularly scheduled production update.
Update: Jan 14: The test pods were updated to 25.01.31 overnight from 25.01.30. Early testing is showing the fix to be in place.
