Field help (SERNUMFPNH) 

This is the serial number of the product.

When a serial number has been entered in the previous column and the quantity to be returned is greater than 1, the serial number end range is automatically calculated by adding the quantity (in stock unit) to the previous number. The stock to be determined matches all the serial numbers within this range. When the quantity to be delivered is a single stock unit, this number is equal to the start serial number.
Specific case: once the stock has been determined, if a '$' sign is displayed in one of the two columns, this means that the chosen serial numbers are not in a row.
