The system will calculate how many copies of the transport label that must be printed, based on the quantity per package registered on the part, and how many parts that have arrived on this order. In this column, you can modify the number of copies before you print the transport labels, if you should need more (or fewer) copies than usual.
If you do not want to print any transport labels at all for a particular part, you should uncheck the check box at the far right on that row.
