• What is the cause and solution for SAP error message MMRP01224 - Backflush not possible as explosion has not been carried out (start RPM) ?

  The SAP error message MMRP01224 indicates that a backflush operation cannot be performed because the explosion of the bill of materials (BOM) has not been carried out. This typically occurs in the context of production orders or process orders where components need to be allocated before backflushing can take place.
  Cause:
  
  BOM Explosion Not Executed: The primary reason for this error is that the system has not processed the BOM explosion for the production order. The explosion is necessary to determine which components are required for the production process.
  Order Status: The production order may not be in the correct status to allow for backflushing. For example, if the order is not released or is in a status that does not permit backflush, this error can occur.
  Configuration Issues: There may be configuration settings in the system that prevent the explosion from being executed properly.
  Missing Components: If the components required for the production order are not available or not defined in the BOM, the explosion may not occur.
  
  Solution:
  
  
  Execute BOM Explosion: Ensure that the BOM explosion has been executed for the production order. This can typically be done by:
  
  Going to the production order and executing the explosion manually if needed.
  Checking the order status and ensuring it is released.
  
  
  
  Check Order Status: Verify that the production order is in a status that allows for backflushing. The order should be released and not in a status that prevents further processing.
  
  
  Review BOM Configuration: Check the configuration of the BOM to ensure that it is correctly set up and that all components are defined. Make sure that the BOM is valid for the material and the production order.
  
  
  Check Component Availability: Ensure that all components required for the production order are available and correctly defined in the system.
  
  
  Consult Documentation: If the issue persists, consult SAP documentation or your internal SAP support team for further troubleshooting steps specific to your configuration.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as CO01 (Create Production Order), CO02 (Change Production Order), or CO03 (Display Production Order) to manage production orders.
  BOM Transaction Codes: Use transaction codes like CS01 (Create BOM), CS02 (Change BOM), or CS03 (Display BOM) to manage BOMs.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  By following these steps, you should be able to resolve the MMRP01224 error and successfully perform the backflush operation.
