Good mornig, Erik! :o)

I've got this doubt, and decided to ask somenoe on line...

Can I use "wildcards" within the value of a parameter, in a parameterized view?

Assume we have a view with two parameters, and in a given situation while running the application, we don't want the second parameter to limit the view, only the first one. How can I symbolize that? Can I put some "wildcard" as the value of the second (un-needed) parameter?

Any help will be greatly appreciated!

TIA :o)
