Let's say that you want to break your computers down by managing all the systems in the Engineering AND Accounting Active Directory Organization Units. With PDQ Inventory Pro, you can easily do this.
Notice that we have created a Collection which has TWO filters. One filter returning all computers in the an OU which contain the name Engineering and another filter returning computers whose OU path in AD contains the word Accounting. Notice also that instead of the default "Match All" operator we are using Match Any.
Here is what our new collection membership looks like. All the member machines are in either the Engineering or Account OU.
