Hi James,   Thank you very much for your answer.   Now it's much more clear for me what is the extend of each of these rules.   What was new for me was your explanation about the "Contact Dttm" field (last day of contact) as I thought the way to interpret "today: -10; -6; -3" was "in the last 10 days and 6 days and 3 days" (before I though the ";" meant "or")   I really appreciate the clarification, it made a huge difference! ...

Art, You can create an implicit AND so that one select points into another select and it take the intersection of the two. I would think you'd have one node that is -30 to 0. You could have another -30 to 0 and change the Rule to No value meets this criteria and run that into a 3rd node which is -360 to -31 where the Rule is left at the default of "One Value Meets This Criteria" You can also have a Select node with -360 to -31 with a second line of AND NOT -30 to 0. This is would still require a 2nd node of just -30 to 0. ... View more

The goal of this refinement is to select specific row for the selected customer/subject id if more than one row is available for that customer / subject ID. ... View more
