The quantity ratio of the bill of material is 1:1:2:4. The first date on which something can be confirmed for all items is October 1, 1997. Using the quantity ratio, we can see that item 25 has the lowest quantity.
Therefore, the following quantities are confirmed for October 1, 1997:
The next date is 6.10 for item 20 but nothing is available for item 20 on that day so the system takes the 8.10 as the next correlation date:
In item 20 nothing is available for item 15 on 10 Oct; or from item 35 on 14 and 16 Oct. so everything is confirmed for item 20 on 20 Oct.
