  The SAP error message /ACCGO/UIS_MSG199 Unit of measure &1 is not allowed for material &2 typically indicates that the unit of measure (UoM) you are trying to use for a specific material is not configured or allowed in the system for that material. This can occur in various scenarios, such as during inventory management, purchasing, or sales processes.
  Cause:
  
  Incorrect Unit of Measure: The unit of measure you are trying to use is not defined for the material in the material master data.
  Configuration Issues: The unit of measure may not be set up correctly in the system, or it may not be assigned to the material in the relevant views (e.g., purchasing, sales, or inventory).
  Material Type Restrictions: Certain material types may have restrictions on which units of measure can be used.
  Unit of Measure Conversion: If the system is expecting a specific unit of measure and you are trying to use a different one without a proper conversion defined, this error can occur.

  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the relevant views (e.g., Basic Data, Purchasing, Sales) to see if the unit of measure is listed.

  Add Unit of Measure:
  
  If the unit of measure is missing, you can add it by using transaction code MM02 to change the material master.
  Navigate to the relevant view and add the required unit of measure.
  
  
  
  Review UoM Configuration:

  Check Material Type Settings:
  
  Review the material type settings to ensure that the unit of measure is allowed for that specific material type.
