How To Fix VHUAP235 - Processing of HUs impossible due to different references

SAP Error Message - Details

• Message type: E = Error

• Message class: VHUAP - Messages for Packing Transaction Applications (FGrp VHUDIAL)

• Message number: 235

• Message text: Processing of HUs impossible due to different references

What causes this issue?

You are trying to process or display several handling units (HUs) at the
same time. Processing HUs can include either packing or unpacking
transactions. The message is cancelled by different references for the i
ndividual handling units.
One of the following reasons may be responsible for you not being able
to process the handling unit:
You are trying to simultaneously process HUs which have references to
different documents (sales order/scheduling agreement, stock transport
order/scheduling agreement or delivery). The document items must also be
identical.
You are trying to pack another material for a HU. This HU already has a
reference to a sales order, an order or a delivery.
You are already processing a HU with reference and want to pack more
material into a newly created HU.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

How to fix this error?

It is not possible to process HUs with different references at the same
time. If it is necessary to process these HUs, you must firstly delete
the existing references for the sales order, order or delivery.
HUs without reference can therefore not be processed any further using
transaction VL10HU.

• What is the cause and solution for SAP error message VHUAP235 - Processing of HUs impossible due to different references ?

  Certainly! Here's a detailed explanation for the SAP error message VHUAP235 - Processing of HUs impossible due to different references:
  
  Error Message
  VHUAP235: Processing of HUs impossible due to different references
  
  Cause
  This error occurs during Handling Unit (HU) processing in SAP when you try to perform an operation (such as packing, unpacking, or handling HU movements) involving multiple Handling Units that have conflicting or different reference documents or reference numbers.
  In SAP, Handling Units are often linked to specific reference documents like delivery documents, production orders, or warehouse tasks. If you attempt to process multiple HUs together that belong to different reference documents, the system prevents this to maintain data consistency and traceability.
  Typical scenarios causing this error:
  
  Trying to pack or unpack HUs that belong to different deliveries or production orders in one step.
  Attempting to post goods movements or warehouse tasks involving HUs with different reference documents.
  Combining HUs with different sales orders or purchase orders in a single operation.
  
  
  Solution
  To resolve this error, you need to ensure that the Handling Units you are processing together share the same reference document or are processed separately according to their references.
  Steps to fix:
  
  
  Check the references of the involved HUs:
  
  Use transaction codes like HU03 (Display Handling Unit) or VL03N (Display Delivery) to check the reference documents linked to each HU.
  Identify which HUs belong to which reference documents.
  
  
  
  Process HUs separately by reference:
  
  Group HUs by their reference documents.
  Perform packing, unpacking, or goods movements separately for each group.
  
  
  
  Correct any incorrect HU assignments:
  
  If an HU is incorrectly assigned to a wrong reference document, investigate and correct the assignment.
  This might involve reversing incorrect postings or reassigning HUs properly.
  
  
  
  Check configuration and custom enhancements:
  
  Sometimes, custom code or specific configuration might enforce strict reference checks.
  Review any user exits or BAdIs related to HU processing that might cause this behavior.
