Webi report prompt selection

Hello All,

I have a requirement in a webi report where I have Manager ID in the prompt of the query. This is a single selection and is a optional prompt. So when the user runs the report and selects a Manager ID in the report it is displayed at the top where I have used a Reportfilter function.

Now for example there are 500 Manager ID's and when the user doesnt select any ID and runs the report the reportfilter shows all the Manager IDs.Is there a way that instead of showing all 500 IDs, it displays ALL when user doesnt select any Manager ID?

Thanks,

Nisha
