  WG126 - Change and reverse not possible at same time! Item: &1
  
  
  Cause:
  This error occurs when you attempt to perform a change and a reversal on the same goods movement item simultaneously in a Goods Movement document (e.g., material document, transfer posting, goods issue, or goods receipt).

  Reverse means canceling or undoing the goods movement.
  
  Trying to do both in one step or transaction leads to this error.
  
  When does it typically occur?
  
  During the processing of material documents in transactions like MB02 (Change Material Document) or when using BAPIs or custom programs that try to change and reverse the same item simultaneously.
  When attempting to reverse a goods movement item that is also being changed in
