  Configuration Settings:

  Ensure that the UoM conversion settings are correctly defined for the material and sales document type.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the material master and sales documents to identify any discrepancies.
  Use transaction codes like SE11 or SE16 to check the relevant database tables for any missing or incorrect entries.
