If part of the quantity on the original line has already  been returned, the program creates the new line with only the quantity  that has not yet been returned. If the full quantity has already been  returned, the program does not create a new document line.
Če je bil del količine v izvorni vrstici že vrnjen, program ustvari novo vrstico s samo tisto količino, ki še ni bila vrnjena. Če je bila vrnjena že celotna količina, program ne ustvari nove vrstice dokumenta.
