• What is the cause and solution for SAP error message HUFUNCTIONS045 - Handling unit with ID &1 already exists in Warehouse ?

  The SAP error message HUFUNCTIONS045 indicates that a handling unit (HU) with the specified ID already exists in the warehouse. This error typically occurs when you attempt to create or process a handling unit that has the same identifier as one that is already present in the system.
  Cause:
  
  Duplicate Handling Unit ID: The most common cause is that the handling unit ID you are trying to create or use is already assigned to another handling unit in the warehouse.

  Solution:
  
  Check Existing Handling Units: Use transaction codes like HU02 (Display Handling Unit) or HU03 (Display Handling Unit with Stock) to search for the existing handling unit ID in the system. This will help you confirm whether the ID is indeed in use.
