Example of How You Resolve Item Constraints Within A Set

Let's say you're planning three orders for the same item, sourced from the same organization. Let's chart out the sales order attributes that are relevant before and after planning. We will review two planning scenarios: in the first, the Pull-in Enabled value is Yes for all three orders, and in the second, we prevent one order from being considered for improvement.

Order Line Number	Item	Requested Date	Item Availability Date	Planned Date	Constraint Rank	Planned Date Without Item
Line 3	Item 3	01/15/2020	01/25/2020	01/25/2020	1	01/22/2020
Line 1	Item 1	01/15/2020	01/22/2020	01/25/2020	2	01/19/2020
Line 2	Item 2	01/15/2020	01/19/2020	01/25/2020	3	01/15/2020

Inferences

• The most constraining line is Line 3, because Item 3 is has the latest item availability date. Because the planned date of a set is the planned date of its most constrained line, the planned date for this set is 01/25/2020. If you remove Line 3 from the set, the planned date for the set becomes 01/22.

• If you remove just Line 1 and Line 2, the planned date will still be 01/25/2020, because the most constraining line, Line 3, is still in the set.

• If you want the set planned on time, you must remove not only Line 2, but also Line 1 and Line 3.
