• What is the cause and solution for SAP error message W_CB240 - Unit of measure &1 not expected ?

  The SAP error message:
  W_CB240 Unit of measure &1 not expected
  typically occurs in the context of SAP's logistics or materials management modules, such as during goods movements, inventory management, or sales order processing, when the system encounters a unit of measure (UoM) that it does not expect or recognize for a particular material or transaction.
  
  Cause
  
  Unexpected Unit of Measure: The unit of measure entered or processed (&1 represents the UoM code) is not valid or not expected for the material or transaction in question.
  Missing or Incorrect UoM Configuration: The unit of measure might not be maintained in the material master or in the relevant customizing settings.
  Mismatch Between UoM and Material Master: The UoM used in the transaction is not assigned or allowed for the material.
  Incorrect Transaction or Process Step: The process step or transaction expects a specific UoM, and the entered UoM does not match the expected one.
  Conversion Issues: If the system tries to convert between units and the UoM is not defined or conversion factors are missing.
  
  
  Solution
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Units of Measure tab.
  Verify that the unit of measure &1 is maintained as a valid UoM for the material.
  If missing, add the required UoM in the material master (using MM02).
  
  
  
  Verify Customizing Settings:
  
  Check the unit of measure settings in SPRO under:
  
  Logistics ? General ? Units of Measure ? Check Units of Measure.
  
  
  Ensure the UoM &1 is defined and active.
  
  
  
  Check Transaction Data:
  
  Verify that the UoM entered in the transaction is correct and consistent with the material master.
  If the transaction expects a base unit of measure or a specific alternative UoM, use that.
  
  
  
  Maintain Conversion Factors:
  
  If the UoM &1 is an alternative UoM, ensure that conversion factors to the base UoM are maintained in the material master.
  
  
  
  Review Process and Documentation:
  
  Confirm that the business process allows the use of the UoM &1.
  If the UoM is not standard or custom, check with the business or master data team.
  
  
  
  Testing:
  
  After corrections, test the transaction again to confirm the error is resolved.
