inventory problems

[sepp]

Hello,

I have 20 different software products in the company.
For each product I have a query, that shows me on wich
machines the product is installed.

How can I build a query that makes the other way:
I chose a computername (creteria prompted value) and
the query shows me, wich of the 20 software products is installed on
this computer? The info of the Resource Explorer is too crowdy.

Thanks a lot
Andi
