Smart SAP Assistant

• What is the cause and solution for SAP error message WER_TEST009 - Base unit KG is not supported ?

  The SAP error message WER_TEST009: Base unit KG is not supported typically occurs in the context of Warehouse Management (WM) or Extended Warehouse Management (EWM) processes, especially when dealing with unit of measure (UoM) conversions or packaging specifications.
  
  Cause
  
  The error indicates that the base unit of measure "KG" (kilogram) is not supported or recognized in the specific warehouse or logistics process.
  This usually happens because the system expects a unit of measure that is defined as a base unit in the material master or warehouse management settings, but "KG" is either:
  
  Not maintained as a base unit in the material master,
  Not allowed in the warehouse process or packaging specifications,
  Or the warehouse process is designed to handle only certain units (e.g., pieces, liters) and not weight units like KG.
  
  
  In some cases, the error arises when the packaging specifications or handling units are defined with KG as the base unit, but the system or process does not support weight as a base unit for handling units.
  
  
  Solution
  
  
  Check Material Master Data:
  
  Go to transaction MM03 and check the Basic Data 1 view.
  Verify the Base Unit of Measure for the material.
  If the base unit is KG, confirm if this is appropriate for warehouse processes.
  If necessary, change the base unit to a supported unit (e.g., PC for pieces) via material master change (MM02), but note that changing base unit is complex and may require material master re-creation or special handling.
  
  
  
  Check Warehouse/Packaging Specifications:
  
  Review packaging specifications in transaction PK03 or relevant EWM packaging configuration.
  Ensure that the base unit used in packaging specifications is supported.
  If KG is used as a base unit in packaging, consider changing it to a supported unit.
  
  
  
  Check Unit of Measure Conversions:
  
  Verify UoM conversions in transaction CUNI or CUNI2.
  Ensure that conversions between KG and other units are correctly maintained.
  
  
  
  Check Warehouse Process Configuration:
  
  In EWM or WM, check if the process or movement types support KG as a base unit.
  Some warehouse processes only support countable units (e.g., pieces) and not weight units.
  
  
  
  Consult SAP Notes:
  
  Search for SAP Notes related to WER_TEST009 for any patches or corrections.
  Sometimes, this error is due to missing configuration or known bugs.

  Typical Scenario:
  
  When creating or processing handling units or packaging specifications, the system validates the base unit of measure.
  If KG is used but not supported, the error WER_TEST009 is triggered.
