Pick Slip Lot Serial

1.We have some issue in Pick slip that we don't Understand, when we print Pick Slip for 100 items,

2.so on FIFO basis system will take the Lot least date Stock first,

3.once stock in Lot finished,

4.it should go to another very next lot having stock and print qty accordingly with different lot no,

5.but it is not doing like that, whatever the Lot it took first time,

6.it will print for all the quantities even lot having less stock,

7.for example First lot have 70 qty stock and we print pick slip for 100 qty, it will print the same First lot no. for all the 100 quantities,
