In BI 4.0, when you create a report on Bex Query (with BICS connection), by default, all the prompts of the BEX query are automatically displayed.
Is there a way to unselect a prompt from the Bex query in the webi prompt screen?
in the webi query panel, there is a 'set variables' button, where you can make variables optional and set a default value etc.
however, i don't think it's possible to suppress/hide it.
You may have to make it a hardcoded filter in Bex query itself.
