  SAP Error Message: WG133
  Message Text:
  
  The quantity to be changed and the quantity in doc. item &1 are the same
  
  Cause
  This message occurs when you attempt to change the quantity of a document item (e.g., in a delivery, goods movement, or sales document), but the new quantity you enter is exactly the same as the current quantity already stored in the document item.
  In other words, the system detects that there is no actual change in the quantity value, so it prevents the update because it is redundant.
  
  Explanation
  
  The system expects a change in the quantity field to trigger an update.
  If the quantity you enter matches the existing quantity, the system considers this as no change.
  This message is a safeguard to avoid unnecessary processing or updates when no real change is made.
  
  
  Solution
  
  Verify the quantity you want to enter: Make sure that the quantity you are trying to change is actually different from the current quantity in the document item.
  If you intended to change the quantity: Enter a different value than the current one.
  If you did not intend to change the quantity: You can simply leave the quantity as is and proceed without making changes.
  Check for user input errors: Sometimes, the user might think they changed the quantity but actually entered the same value by mistake.
  
  
  Related Information
  
  This message is common in transaction codes related to delivery processing (e.g., VL02N), goods movements (e.g., MIGO), or sales order processing (e.g., VA02).
  It is a standard message to prevent unnecessary updates and maintain data integrity.
  If you want to force an update for other fields without changing the quantity, ensure that the quantity field is not modified or left unchanged.
  If you are using custom programs or user exits/BADIs that modify quantities, ensure that they do not attempt to set the quantity to the same value unnecessarily.
