I just created a bunch of output set elements. They're all attributes (I'm being good, and have created a new "Query Element Group" for our Attribute query elements). Some are multiple value, others are single value, all carefully set. The multiple value output elements are showing up as such in output set builder, but all of the single value attributes are showing up with the -[0]+ control as though they were aggregate values. Apart from defining the data_select column with "!.key_value", I don't know how to convince Tessitura that they are not aggregate values. Anyone else seeing this? I'm seeing it with the built in Attributes group as well.
Also, my built-in attributes group is full of duplicates: one set is normally defined for v14.1, the other has the old "deprecated_where", etc. columns filled in. Anyone else have this? Should I just trim out the ones with the "deprecated" columns?
I've created a few new elements. I've seen problems with the custom_1, custom_2..., custom_9 coming off of orders and contribution. However, I've not exactly seen what I think you are saying.
What version of Tessitura are you on? If I remember correctly you have Analytics so something 15.___.___I'd guess.
14.1
