If part of the quantity on the line has already been  returned (or sold, or otherwise consumed), the program creates the new  line with only the remaining quantity. If the full quantity on the line  has been used, the program does not create a new line.
Če je bil del količine v vrstici že vrnjen (ali prodan ali kako drugače porabljen), program ustvari novo vrstico samo s preostalo količino. Če je bila porabljena celotna količina v vrstici, program nove vrstice ne ustvari.
