For a receipt with a Demand of 3.00
products, one product has already been assigned
a serial number in the Open: Stock move pop-up window.
So, in the Import Lots pop-up window, two serial numbers, 124
and 125
are
assigned to the remaining products by entering the following in the Lots/Serial
numbers input field:
124
125
The Keep current lines option is selected to add these two serial numbers in

, that has already been assigned.
