• What is the cause and solution for SAP error message /SCWM/HUFUNCTIONS121 - No conversion between &1 and &2 found ?

  The SAP error message /SCWM/HUFUNCTIONS121 No conversion between &1 and &2 found typically occurs in the context of handling Handling Units (HUs) in the SAP Extended Warehouse Management (EWM) module. This error indicates that there is an issue with the conversion between two different units of measure (UoM) or handling unit types.
  Cause:
  
  
  Unit of Measure (UoM) Configuration: The error often arises when there is no defined conversion factor between the two units of measure involved in the operation. For example, if you are trying to convert from a handling unit type that uses one UoM to another that uses a different UoM, and there is no conversion defined in the system.
  
  
  Handling Unit Type Mismatch: The error can also occur if there is a mismatch in the handling unit types being used in the transaction. If the system expects a certain type of handling unit and receives another, it may not know how to convert between them.
  
  
  Master Data Issues: There may be issues with the master data configuration for the materials or handling units involved, such as missing or incorrect UoM settings.
  
  
  Solution:
  
  
  Check UoM Configuration:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) in SAP.
  Verify that the necessary conversion factors between the UoMs are defined. If not, you will need to create the appropriate conversion entries.
  
  
  
  Review Handling Unit Types:
  
  Ensure that the handling unit types being used in the transaction are compatible. Check the configuration in the handling unit management settings.
  You can check the handling unit types in the customizing settings under Logistics Execution -> Handling Unit Management -> Define Handling Unit Types.
  
  
  
  Master Data Review:
  
  Check the material master data for the materials involved in the transaction. Ensure that the UoM settings are correct and that the handling unit types are properly assigned.
  You can use transaction code MM03 to view the material master data.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to handling units and UoM conversions for any specific guidance or updates that may apply to your version of SAP EWM.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the process to identify where the conversion is failing. This may require assistance from a technical consultant or SAP support.
