WJ200 - Details

• Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WJ200 Additional &1 has not been created as a material
  
  Meaning / 
  Cause:
  This warning message occurs when you try to use or reference an additional material (also called an alternative or substitute material) in a process (such as production order, sales order, or BOM) but the system cannot find this additional material in the material master. In other words, the additional material number you entered does not exist as a valid material in the SAP system.
  
  &1 is a placeholder for the material number that is missing.
  The system expects that all materials referenced (including additional materials) must be created and maintained in the material master (transaction MM01/MM02).
  This message typically appears during BOM processing, production order creation, or when using alternative materials functionality.
  
  
  Common Scenarios:
  
  You have defined an additional material in a BOM or production order, but the material master record for that
