Follow these steps to ensure CPF is calculated correctly:
Reprocess the 1st Half.
Some 1st half settings may still be active.
Delete and reprocess the 1st half data to remove any lingering calculations or formulas.
Reprocess the 2nd Half.
Disable 1st Half Settings.
Navigate to Housekeeping, Parameter Setup, Control.
De-select all 1st half-enabled functions and apply the changes.
Once completed, the 1st half will no longer be processed, preventing incorrect calculations.
