• What is the cause and solution for SAP error message CN751 - Material & is not for planned independent requirements ?

  The SAP error message CN751 ("Material & is not for planned independent requirements") typically occurs in the context of production planning and control when you are trying to create or process planned independent requirements (PIR) for a material that is not set up to allow them. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Material Master Settings: The material in question is not configured to allow planned independent requirements. This can happen if the material type or the specific settings in the material master do not support PIR.
  Material Type: Certain material types (e.g., non-stock materials) do not allow for planned independent requirements.
  Planning Strategy: The planning strategy assigned to the material may not support PIR. For example, if the strategy is set to "Make to Stock" (MTS) or "Make to Order" (MTO) without the necessary configurations, it may lead to this error.
  Plant Settings: The plant settings for the material may not be configured to allow for independent requirements.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03) and check the relevant views (especially the MRP view).
  Ensure that the "MRP Type" is set correctly. For example, it should be set to a type that allows for planned independent requirements (like "PD" for MRP).
  Verify that the "Planning Strategy" is appropriate for your needs. If you need PIR, consider using strategies like "Make to Stock" (MTS) or "Make to Order" (MTO) that support it.
  
  
  
  Adjust Planning Strategy:
  
  If the current planning strategy does not support PIR, you may need to change it. This can be done in the material master under the MRP view.
  Ensure that the strategy allows for independent requirements.
  
  
  
  Check Configuration:
  
  If you have the necessary authorizations, check the configuration settings in SPRO (Customizing) under the Production Planning section to ensure that the material type and planning strategy are set up correctly to allow for PIR.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidance on the material type and planning strategy configurations.
  
  
  
  Testing:
  
  After making changes, test the creation of planned independent requirements again to ensure that the error is resolved.
