• What is the cause and solution for SAP error message MPE_WI_EMB_MSGS021 - Backflushed components cannot be added as input ?

  The SAP error message MPE_WI_EMB_MSGS021 indicates that backflushed components cannot be added as input in a production order or process. This typically occurs in the context of production planning and execution, particularly when dealing with backflushing in SAP.
  Cause:
  The error arises when you attempt to add components that are set up for backflushing to the input list of a production order or process. Backflushing is a method where components are automatically deducted from inventory when the production order is confirmed, rather than being manually issued to the order. The system does not allow you to manually add these components as inputs because they are already accounted for in the backflushing process.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review the Production Order: Check the production order to ensure that the components you are trying to add are indeed set up for backflushing. If they are, you should not attempt to add them manually.
  
  
  Adjust Component Settings: If you need to change how components are handled, you may need to adjust the settings in the material master or the bill of materials (BOM) for the relevant components. Ensure that the components are correctly defined for backflushing.
  
  
  Use Manual Issue: If you need to issue components manually, consider changing the backflush setting for those components in the BOM or production order. This may involve changing the component type or the backflush indicator.
  
  
  Check Configuration: Ensure that the configuration for backflushing in your SAP system is set up correctly. This includes checking the production version and the settings in the material master.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling backflushing and production orders.
  
  
  Contact Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your specific configuration and business processes.
  
  
  Related Information:
  
  Backflushing: Understand the concept of backflushing in SAP, which is used to simplify the inventory management process by automatically deducting components from stock when production is confirmed.
  Production Order Management: Familiarize yourself with the production order lifecycle in SAP, including how components are managed and issued.
  Material Master and BOM: Review the settings in the material master and BOM to ensure they align with your production processes and requirements.
  
  By following these steps, you should be able to address the error and ensure that your production processes run smoothly.
