I'm not sure I completely understand. Are these table valued function parameters all in the same workbook? How would you like the user to be prompted? Could you go into a little more detail about the desired functionality? Thanks!
Say I have function f1(int, date, date), and the call would be:
SELECT * FROM f1(id, start_date, end_date)
When a user opens the workbook and refreshes it, I would like Tableau to prompt the user for the three function parameters, then render the report / viz.
