Looking at the way you walk me through a database connection by selecting tables, I dont yet see a way to connect and run a stored prodecure as a data source. Is that even possible in this product? Is the script syntax similar to Qlik View?
I use stored procedures all the time and you just connect to database as how you would connect through an ODBC connection, then insert a connection string. After that if you know the stored procedure name, you can type exact the same way in the screenshot.
So I am connecting to Test_Server and running a stored procedure called test.
