  Error Message
  VHU01131: Do not enter packing instructions twice
  
  Cause
  This error occurs when the system detects that packing instructions are being entered more than once for the same handling unit or packing process. In SAP's Handling Unit Management (HUM), packing instructions are meant to be unique per handling unit or packing step. Entering them twice can cause inconsistencies or redundant data in the packing process.
  Common scenarios causing this error:
  
  Attempting to assign packing instructions to a handling unit that already has them.
  Trying to re-enter or duplicate packing instructions during packing or handling unit creation.
  Custom code or user actions that inadvertently trigger multiple entries of packing instructions.
  
  
  Solution
  To resolve this error, consider the following steps:
  
  
  Check Existing Packing Instructions:
  
  Verify if packing instructions have already been assigned to the handling unit.
  Use transaction codes like HU02 (Change Handling Unit) or HU03 (Display Handling Unit) to review existing packing instructions.
  
  
  
  Avoid Duplicate Entry:
  
  Ensure that packing instructions are entered only once per handling unit.
  If you need to modify packing instructions, update the existing ones instead of creating new entries.
  
  
  
  Review Process Flow:
  
  Confirm that the packing process or program logic does not attempt to assign packing instructions multiple times.
  If using custom developments or enhancements, check the code to prevent duplicate assignment.
  
  
  
  Clear or Delete Incorrect Entries:
  
  If duplicate packing instructions exist, delete or correct them before proceeding.
  
  
  
  Consult SAP Notes:
  
  Check for any SAP Notes related to handling unit packing instructions for your SAP version.
