W_012 - Details

• SAP Error Message:
  W_012 Full products are not allowed as component materials
  
  
  Cause:
  This warning message occurs when you try to use a full product (a finished product or a sales item) as a component in a Bill of Materials (BOM). In SAP, components in a BOM are typically raw materials, semi-finished products, or assemblies, but not full finished products that are meant to be sold as standalone items.
  The system restricts the use of full products as components to avoid inconsistencies in production planning, costing, and inventory management. Using a full product as a component can lead to incorrect BOM structure and planning errors.
  
  Explanation:
  
  Full products are materials flagged as finished goods or sales items.
  Component materials in a BOM should be raw materials, semi-finished goods, or assemblies.
  The system checks the material master data and issues this warning if a full product is assigned as a component.
