I'd like to save the user's current selection via a procedure (click on button to save), in order to be able to restore them later (click on button to retrieve and set). This way user's would have their own saved queries (I intend to limit the amount to 5 and have 5 Buttons).
What I've tried doing is storing the value of "@Selection_Ex" see Substitution formulas in a text cube with a dataflow. But that does not work as there is no value.
Any ideas / input?
