Exclusion Confusion

This scenario arises when:

•       Either:

o  A criterion exists at standard selection rule root level, and the criterion’s resolution table does not match the standard selection rule’s resolution table.

o  A criterion exists at criteria list level, and the criterion’s resolution table does not match the criteria list’s resolution table.

•       The criterion is excluded.

The potential ambiguity here revolves around the user’s understanding of the manner in which RPI handles an exclusion at a mismatched resolution table.  For example, will these rules exclude:

•       Customers with one blue product, even if they have other, non-blue products?

•       Customers who only have blue products.

The answer is the first option – these rules will exclude anybody with a blue product, even if they have products of other colors.

Note that creating this scenario is somewhat convoluted, as, by default, a criterion with a resolution table that differs from its parent rule’s or list’s resolution or resolution table will automatically be created in its own criteria list, with a resolution table matching that of the rule.  As such, manual manipulation of resolution level or resolution table is required for the warning to be displayed in the first place.
