• What is the cause and solution for SAP error message VHU01164 - Reference changed for selected HU ?

  SAP Error Message:
  
  VHU01164 - Reference changed for selected HU
  
  Cause:
  This error occurs when you try to perform an operation on a Handling Unit (HU) whose reference document or reference data has been changed or updated in the system after the HU was selected. Essentially, the system detects that the HU's reference (such as a delivery document, production order, or sales order) has been modified, and therefore the HU is no longer consistent with the original reference data used when the HU was selected.
  This can happen in scenarios like:
  
  The HU was selected based on a particular reference document, but that document has since been changed (e.g., delivery quantity changed, document status updated).
  The HU is linked to a document that has been deleted or replaced.
  The HU's reference assignment was changed by another user or process in the system.
  
  
  Solution:
  To resolve the error, you should:
  
  
  Check the Reference Document:
  
  Verify the current status and data of the reference document linked to the HU.
  Confirm if any changes were made to the document after the HU was selected.
  
  
  
  Refresh or Re-select the HU:
  
  Deselect the HU and re-select it to ensure the system reads the latest reference data.
  Alternatively, refresh the transaction or screen to reload the current data.
  
  
  
  Synchronize Data:
  
  If the reference document was changed intentionally, ensure that the HU assignment is updated accordingly.
  If the HU is no longer valid for the changed reference, you may need to remove or reassign the HU.
  
  
  
  Check for Locks or Parallel Changes:
  
  Ensure no other user or process is simultaneously modifying the HU or its reference document.
  Wait for any background jobs or updates to complete before retrying.
  
  
  
  Consult SAP Notes or Support:
  
  If the problem persists, check SAP Notes for any known issues related to this message.
  Contact SAP support with detailed information about the HU and reference document.
