Subformulas are included in the check

In the Context tab, the Context Type values initially get populated from the Formulas selected for the Guideline Check.

Subformulas items get exploded and combined with the items from the parent formula, so this combined Qty % gets used in the Guideline Check.

Separate guidelines can also be created for manufacturing items, as they are treated as an item. If a manufacturing item is used at multiple levels, the combined Qty % is used in the Guideline Check. Here is an example of a manufacturing item guideline: Item X is not usable after Date xx/xx/xxxx.
