• What is the cause and solution for SAP error message MD133 - Simulation planned orders cannot be firmed ?

  The SAP error message MD133, which states "Simulation planned orders cannot be firmed," typically occurs in the context of the Material Requirements Planning (MRP) process. This error indicates that the system is trying to firm planned orders that are in simulation mode, which is not allowed.
  Cause:
  
  Simulation Mode: The planned orders you are trying to firm are created in simulation mode. This means they are not yet finalized and are meant for analysis or planning purposes only.
  Order Status: The planned orders may have a status that does not allow them to be firmed. For example, they might be marked as "in process" or "not released."
  Configuration Settings: There may be configuration settings in the MRP or production planning module that prevent the firming of simulation orders.
  
  Solution:
  
  Check Order Type: Ensure that the planned orders you are trying to firm are not in simulation mode. You can do this by checking the order type and its status in the system.
  Change to Firm Orders: If you need to firm the planned orders, you should first convert them from simulation to firm orders. This can typically be done through the MRP run or by manually changing the order status.
  Review MRP Settings: Check the MRP settings in your SAP configuration to ensure that the system is set up correctly for firming planned orders. This may involve reviewing the settings for planned order types and their allowed statuses.
  Use the Correct Transaction: Make sure you are using the correct transaction code for firming planned orders. The typical transaction for firming planned orders is MD16 (Firm Planned Orders) or MD15 (Convert Planned Orders).
  Consult Documentation: Refer to SAP documentation or help files for specific instructions related to your version of SAP, as the steps may vary slightly depending on the system configuration.
  
  Related Information:
