• What is the cause and solution for SAP error message /CWM/LES104 - Unit of measure is not permitted as parallel unit of measure ?

  The SAP error message /CWM/LES104 Unit of measure is not permitted as parallel unit of measure typically occurs in the context of warehouse management or logistics execution when there is an issue with the unit of measure (UoM) configuration for a material or product.
  Cause:
  
  Incorrect UoM Configuration: The unit of measure being used is not set up correctly in the system. This can happen if the UoM is not defined as a parallel unit of measure in the material master data.
  Material Master Settings: The material master may not have the necessary settings for parallel units of measure, which are used for conversions between different units of measure.
  Incompatibility: The UoM being used may not be compatible with the operations being performed, such as picking, packing, or shipping.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the "Units of Measure" view to ensure that the parallel unit of measure is correctly defined.
  Ensure that the UoM you are trying to use is listed as a parallel unit of measure.
  
  
  
  Define Parallel Units of Measure:
  
  If the UoM is not defined, you may need to add it. This can be done in the material master or through the configuration settings.
  Use transaction code OMN3 to define the parallel units of measure for the relevant material types.
  
  
  
  Review UoM Conversion Settings:
  
  Ensure that the conversion factors between the base unit of measure and the parallel unit of measure are correctly set up.
  Check the conversion settings in the material master under the "Units of Measure" section.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to unit of measure settings in the context of your specific SAP version and module.
  
  
  
  Testing:
  
  After making changes, test the process again to see if the error persists.
