  The SAP error message M3758 indicates that a unit of measure (UoM) for a specific material is not maintained in the system. This error typically occurs when you attempt to perform a transaction involving a material that does not have a defined unit of measure in the material master data.
  Cause:
  
  Missing Unit of Measure: The primary cause of this error is that the material master record does not have a unit of measure defined for the specific UoM you are trying to use.
  Incorrect Material Master Data: The material may not have been set up correctly, or the relevant UoM may not have been assigned during the creation of the material master.
  Configuration Issues: There may be issues with the configuration of the material types or UoM settings in the system.

  Check Material Master Data:

  Ensure that the UoM is valid and corresponds to the material type.
  
  
  
  Check UoM Conversion:
  
  If you are using multiple units of measure, ensure that the conversion factors are correctly defined in the material master.
  You can check this in the "Units of Measure" view in the material master.
