This is a common issue in SAP systems, especially when dealing with materials or inventory management.
  Cause:
  
  Missing Unit of Measure: The most straightforward cause is that the field for the unit of measure is left blank when it is required.

  Data Entry Error: Users may inadvertently skip the unit of measure field or enter an invalid value.
  Custom Development: If there are custom programs or enhancements, they may not be handling the unit of measure correctly.

  Check Material Master Data: If you are working with a material, verify that the material master data has the appropriate units of measure defined. You can do this by:

  Checking the "Basic Data" and "Purchasing" views for the unit of measure settings.
