Hello all, I have an expression rule which looks up (via query) and then re

A minor adjustment to Andrew's response. Firstly, in this case it wouldn't make a difference if you use with() or load() - forum.appian.com/.../Evaluation_Functions. What I would do is with( mycdt: <expression to initialize>, if(not(<corner case exp>), mycdt, type!CDT_NAME(field1: mycdt.field1, field2:mycdt.field2 ..... ) ) You need the type! constructor to cast your results to the CDT type. If you have never used a type constructor, I would recommend going to the expression editor and seeing what happens when you write type!CDT_Name(). Then play around with that...do type!CDT_Name(field1: "test") etc. Hope this helps.
