VHUCHG001 - Details

• The SAP error message VHUCHG001 indicates that a Handling Unit (HU) cannot be changed because it contains more than one material item. This typically occurs in the context of handling units in SAP Extended Warehouse Management (EWM) or SAP Logistics Execution (LE) when trying to modify a handling unit that has multiple items associated with it.
  
  Cause:
  The error arises because the system restricts changes to handling units that contain multiple material items. This is a safeguard to ensure data integrity and prevent inconsistencies in inventory management. When a handling unit has more than one item, certain operations (like changing the handling unit's attributes) are not allowed.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Split the Handling Unit:
  
  If you need to change the handling unit, you can split it into multiple handling units, each containing a single material item. This can be done using the transaction code HU02 (Change Handling Unit)
