• What is the cause and solution for SAP error message KN422 - Material & is not a co-product ?

  The SAP error message KN422 ("Material & is not a co-product") typically occurs in the context of production planning and inventory management when dealing with co-products in a production process. This error indicates that the material you are trying to process is not defined as a co-product in the system, which is necessary for certain production scenarios.
  Cause:
  
  
  Material Master Configuration: The material in question is not set up as a co-product in the material master data. Co-products are materials that are produced simultaneously in a production process and are typically defined in the production order or bill of materials (BOM).
  
  
  Production Order Settings: The production order may be configured incorrectly, or the co-product settings may not be properly defined in the order.
  
  
  BOM Configuration: The bill of materials (BOM) for the production process may not include the material as a co-product.
  
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03) for the material in question.
  Verify that the material is set up correctly and check the "Co-Product" indicator in the relevant views (e.g., Basic Data, MRP, etc.).
  
  
  
  Review BOM:
  
  Check the BOM associated with the production order (transaction code CS03).
  Ensure that the material is included as a co-product in the BOM. If it is not, you may need to modify the BOM to include it.
  
  
  
  Production Order Configuration:
  
  Review the production order (transaction code CO03) to ensure that the co-products are correctly defined.
  If necessary, create a new production order with the correct co-product settings.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific instructions on how to set up co-products in your version of SAP.
  
  
  
  User Authorization:
  
  Ensure that you have the necessary authorizations to make changes to the material master, BOM, or production orders.
