A selection window accessed by right click on the field is used to select a lot number.
It is also possible to enter a lot number which does not exist in stocks.
A message then informs the user that no lot exists. This alternative is provided so it is possible to record a lot number that has never been entered even though the goods are physically available. This method can only be applied when negative stock is authorized for the product and when the delivery transaction is set up with no stock determination. In the case of a delivery transaction with stock determination, this lot is only considered if the product if in complete shortage (the detailed allocation algorithm will attempt to allocate stock first).
