  SAP Error Message: VHUAP016
  Text: It is only possible to change HUs that have not been GR posted.
  
  
  Cause:
  This error occurs when you try to change (modify) a Handling Unit (HU) that has already been Goods Receipt (GR) posted in the system. Once an HU is GR posted, it is considered as part of the inventory and the system locks it from further changes to maintain data integrity and consistency in warehouse and inventory management.
  
  Explanation:
  
  Handling Unit (HU): A physical unit (like a box, pallet) identified uniquely in SAP WM/EWM.
  GR Posting: When goods are received and posted into inventory, the HU status changes to "GR posted."
  After GR posting, the HU is linked to inventory documents and stock, so changes to the HU (like contents, packaging, or identification) are restricted.
  
  
  
  Solution:
  
  
  Do not change HUs after GR posting: If you need to make changes, consider the following
