VHU01087 - Details

• SAP Error Message:
  VHU01087 - "Only one HU prototype can be created in the upper packing level"
  
  
  Cause:
  This error occurs during handling unit (HU) creation or packing processes in SAP when the system detects that more than one HU prototype is being created or assigned at the same upper packing level. In SAP's packing structure, each upper packing level (e.g., a pallet or carton) can only have one HU prototype assigned to it. Attempting to create multiple HU prototypes at the same upper packing level violates this rule, triggering the error.
  In other words:  
  
  The system expects a single HU prototype per upper packing level.  
  Multiple HU prototypes are being created or assigned at the same level, which is not allowed.
  
  
  When does it typically occur?
  
  During packing or repacking processes in Warehouse Management (WM) or Extended Warehouse Management (EWM).  
  When creating handling units in Sales and Distribution (SD) or Logistics Execution
