Bex WAD - Dynamically display TABS

Dear Experts,

I have a requirement to dynamically display TABS in a report. I am not aware of how to do that and any help would be greatly appreciated. I had designed my TABS as fixed and each TAB has a query with predefined default variable. However, the client wants the variable to be available for selection with multiple options and only have the TABS displayed for the selected values in the variable screen. We are on BI 7.

Any ideas on how to solve this?

Thanks,

Rue.
