Ajuda p/o campo (LOTPNH) 

Ce champ indique le lot associé à ce mouvement de stock.

In manual return line creation, or when the stock to issue is not determined, you can enter an existing lot number on the site where the return is performed, provided that the product is lot managed. Click the Actions icon to display the selection window of the lot number. You can also enter a lot number that does not exist in the stock, if necessary. A message informs you that the lot does not exist. This allows you to save a lot number that has not been entered yet, even though the goods are physically available. This operating mode can only be used if the product has negative stocks authorized.
