  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 options:
  
  Reverse the GR posting: If the change is critical and must be done on the HU, reverse the goods receipt posting first (using transaction like MIGO with reversal or cancel GR).
  Create a new HU: Instead of changing the existing HU, create a new HU with the desired changes and handle the stock transfer accordingly.
  Use appropriate processes: For changes after GR, use warehouse movements or stock transfer processes that are allowed by the system.
  
  
  
  Check HU status: Before attempting changes, verify the HU status to ensure it is not GR posted.
