Hello expert,
I want to design a parameter with multiple values. when I select a value from "available values" box, and click "right arrow" to move it to "selected values" box, there should be multiple values showed in "selected values" box. because the values in the "available values" box are amalgamated subscriber, but we want to show all subscribers subordinated to this amalgamated subscriber in the "selected values" box.
all those subscriber data are coming from a physical table, and also this almagamtion relationship can be derived from this table by sql.
Many Thanks,
