  Error Message
  WH044: More than one SAP unit of measurement exists for ISO code &
  
  The & is a placeholder for the ISO unit of measurement code.
  
  
  Cause
  This error occurs when SAP finds more than one internal SAP unit of measurement (UoM) assigned to the same ISO unit of measurement code in the system. 
  
  SAP uses ISO codes as a standard reference for units of measurement.
  However, internally, SAP allows multiple units of measurement that can share the same ISO code.
  When a process (e.g., goods movement, delivery, or inventory management) tries to determine the SAP unit of measurement based on the ISO code, SAP cannot decide which one to use because multiple units are linked to the same ISO code.
  This ambiguity causes the system to throw the WH044 error.
