WR101 - Details

• SAP Error Message:
  WR101: Material & has no variants
  
  
  Cause:
  This error occurs when you try to perform an operation that requires the material to have variants (e.g., selecting a variant configuration or accessing variant-specific data), but the material master record does not have any variants assigned or maintained.
  In SAP, a "variant" typically refers to a specific configuration or version of a material that differs in certain characteristics (e.g., size, color, features). If the material is expected to have variants (e.g., in variant configuration or variant BOM scenarios) but none exist, the system throws this error.
  
  When does it occur?
  
  When working with configurable materials (class type 300 or 400) but no variant characteristics or variant data are maintained.
  When trying to create or process sales orders, production orders, or BOMs that require variant data for the material.
  When using variant configuration (LOVC, VC) and the material is not properly set up with variant characteristics or variant
