  Error Message
  WS056: Conversion factor replaced by one already defined
  
  Cause
  This error occurs in SAP when you try to define or maintain a unit of measure (UoM) conversion factor that conflicts with an existing conversion factor already defined for the same unit of measure pair.
  In other words, SAP already has a conversion factor defined between two units of measure, and you are attempting to enter a different conversion factor for the same unit pair. SAP does not allow multiple different conversion factors for the same unit pair because it would create ambiguity in quantity conversions.
  
  When does it occur?
  
  When maintaining units of measure in transaction CUNI (Units of Measure).
  When creating or changing material master data where unit conversions are involved.
  When importing or updating units of measure via data migration or customization.
  When defining alternative units of measure
