• What is the cause and solution for SAP error message VHU01156 - Handling unit changed ?

  SAP Error Message:
  
  VHU01156 - Handling unit changed
  
  Cause:
  This error message typically occurs in the context of Handling Unit Management (HUM) in SAP when there is an inconsistency or unexpected change detected in the handling unit during processing. Specifically, it means that the handling unit (HU) being processed has been changed or modified in a way that is not allowed or expected at that point in the transaction.
  Common scenarios include:
  
  The handling unit was altered (e.g., contents changed, packaging changed) after it was already processed or confirmed.
  The handling unit data in the system does not match the physical handling unit being processed.
  An attempt to post goods movement or delivery with a handling unit that has been changed or is inconsistent with the system records.
  Handling unit status or assignment has changed unexpectedly during processing.
  
  
  Solution:
  To resolve the VHU01156 error, consider the following steps:
  
  
  Check Handling Unit Status:
  
  Verify the current status of the handling unit in the system (transaction HUMO, HUMO02, or via the Handling Unit Monitor).
  Ensure the HU is not locked, blocked, or already processed in a way that conflicts with the current transaction.
  
  
  
  Verify Handling Unit Contents:
  
  Confirm that the contents of the HU (materials, quantities) match the system records.
  If the physical HU was changed (e.g., items added or removed), update the system accordingly before proceeding.
  
  
  
  Recreate or Adjust Handling Unit:
  
  If the HU is inconsistent or corrupted, consider deleting and recreating the handling unit.
  Alternatively, adjust the HU contents or packaging data to align with the physical HU.
  
  
  
  Check Transaction Flow:
  
  Ensure that the handling unit is being processed in the correct sequence.
  For example, do not try to change a HU after it has been confirmed or posted in delivery or goods movement.
  
  
  
  Review Custom Enhancements or User Exits:
  
  If custom code or user exits are involved in handling unit processing, verify that they do not cause unintended changes to the HU.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes that might address known bugs or provide patches related to handling unit inconsistencies.
