Summary :
This SAP Note discusses the firming/fixing logic in APO for planned and production orders. Key points include the inability to firm individual components, though component-level firming indicators do appear when changes are made. The "Output Firmed" indicator is discussed, particularly why it behaves differently in scenarios like manual order adjustments or purchase requisitions. For users needing to enforce firming through manual date changes on the scheduling board, implementing the BAdi /SAPAPO/CDPS_FDISHEU is advised, following the outlined method to ensure orders don't revert based on MRP runs. Additionally, why "PP-Firmed" is not persistently visible due to its dynamic determination based on intensive data operations is clarified.
