WTADDI444 - Details

• The SAP error message:
  WTADDI444 External additional &1 is not assigned to any internal
  typically occurs in the context of Warehouse Management (WM) or Inventory Management (IM), especially when dealing with additional units of measure (UoM) or unit conversions.
  
  Cause
  
  The error indicates that an external additional unit of measure (represented by &1 in the message) used in a transaction or master data is not linked or assigned to any internal unit of measure in the system.
  In SAP, additional units of measure must be mapped to an internal unit of measure to allow proper conversion and processing.
  This usually happens when:
  A material master has an additional unit of measure defined, but the system does not have a corresponding internal unit assigned.
  During goods movement or warehouse processes, an external unit is referenced that the system cannot interpret because the mapping is missing.
  Customizing for units of measure or unit conversions is incomplete or inconsistent.
