• What is the cause and solution for SAP error message WG021 - Unit of measure for store order &, material & cannot be found ?

  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 settings.
  Customizing or master data inconsistencies between the warehouse management system (WM) and inventory management (IM).
  The unit of measure is not maintained in the relevant organizational level (plant, storage location).
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Basic Data 1 and Additional Data tabs for the units of measure maintained.
  Verify the Base Unit of Measure and any alternative units of measure.
  
  
  
  Check Units of Measure in Warehouse Management:
  
  Use transaction LX02 or LS24 to check warehouse stock and units of measure.
  Ensure that the unit of measure used in the store order matches the units maintained in WM.
  
  
  
  Maintain Units of Measure if Missing:
  
  Use transaction CUNI to maintain units of measure if the required UoM is missing.
  Use transaction MM02 to add or correct units of measure in the material master.
  
  
  
  Check Customizing Settings:
  
  Verify the settings in SPRO under Logistics Execution ? Warehouse Management ? Master Data ? Define Units of Measure.
  Ensure that the units of measure are properly defined and assigned.
  
  
  
  Consistency Check:
  
  Run consistency checks between IM and WM data.
  Ensure that the unit of measure in the store order corresponds to the unit of measure maintained in the material master and warehouse management.
  
  
  
  Recreate or Correct Store Order:
  
  If the store order was created with an incorrect or missing unit of measure, correct the order or recreate it with the correct UoM.
