  SAP Error Message:
  
  WSTRN202 No customizing is maintained for structured materials
  
  Cause
  This error occurs in SAP when you try to process or use structured materials (i.e., materials with a Bill of Materials - BOM) in a scenario where the necessary customizing settings for structured materials have not been maintained or activated.
  Specifically, the system expects certain configuration/customizing entries related to structured materials (e.g., BOM usage, item categories, or other related settings) to be present in the system. If these are missing or incomplete, the system cannot proceed and throws this error.
  
  When does it typically occur?
  
  During production order creation or processing.
  When using structured materials in sales or delivery documents.
  When running MRP or other planning transactions involving structured materials.
