• What is the cause and solution for SAP error message C1015 - Unit of measure & does not exist ?

  The SAP error message C1015, which states "Unit of measure & does not exist," typically occurs when the system cannot find the specified unit of measure (UoM) in the relevant master data. This can happen in various contexts, such as during the creation of material master records, sales orders, or inventory management processes.
  Causes:
  
  Missing Unit of Measure: The specified unit of measure has not been defined in the system.
  Incorrect Configuration: The unit of measure may not be correctly configured in the relevant tables or settings.
  Data Entry Error: There may be a typo or incorrect entry when specifying the unit of measure.
  Inactive UoM: The unit of measure might be inactive or not allowed for the specific material or transaction type.
  
  Solutions:
  
  
  Check UoM Configuration:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) or OMN1 (Define Units of Measure) to check if the unit of measure exists in the system.
  If it does not exist, you will need to create it.
  
  
  
  Create Missing UoM:
  
  If the unit of measure is missing, you can create it using the transaction code CUNI or through the relevant configuration path in SPRO (SAP Reference IMG).

  Verify Material Master Data:
  
  Check the material master data using transaction code MM03 (Display Material) to ensure that the unit of measure is correctly assigned to the material.
  If the UoM is not assigned, you may need to update the material master using MM02 (Change Material).
