WG021 - Details

• Certainly! Here's a detailed explanation for the SAP error message WG021:
  
  SAP Error Message: WG021
  Text: Unit of measure for store order &, material & cannot be found
  
  
  Cause:
  This error occurs when the system tries to process a store order (such as a warehouse or inventory movement order) for a specific material, but it cannot find the unit of measure (UoM) assigned or valid for that material in the context of the store/order.
  In other words, the system expects a unit of measure to be defined for the material in the relevant organizational context (e.g., plant, storage location, or warehouse), but this UoM is missing or not maintained.
  
  Common Scenarios Leading to WG021:
  
  The material master does not have the required unit of measure maintained.
  The unit of measure used in the store order is not consistent with the units maintained in the material master.
  The unit of measure is missing in the warehouse management or inventory management
