I'm trying to create the calculation in which one of the fields can be inputted manually by the user. So ideally it should be like a table (or field) on the working page, where users can insert data manually and other graph\table will be recalculated automatically based on this insertion. Can it be done somehow? I'll appreciate the advice.
Create a parameter - it will do a single value only though, you'd have to create a few of them if you want to do several fields.
