Typically a case statement contains a list of mutually exclusive values. In your expression there is more that one member that returns the same value. So R&R is returning the last value in the list that meets the condition rather than the first value in the list.__For example the expression:__CASE(1,1,1,1,2,3)__returns a 2____and __CASE(1,1,1,1,2,1,3,4)__returns a 3____I checked the doc for the function and it does not specifically document how duplicates are handled.____Kathleen__R&R Support__
