I am using OWC on installed software Cube. I select Computer count, then computer name on rows and then Software installed in the columns.
We have inventory run every evening on our servers and they are not set to exclude and folders. After speaking to the business they don't need the report so granular and they don't need to know what server has what, just what we have installed as this will be used to cost out building a DR site.
I tried the install files link cube and it is too granular (pain i know) as this resulted in over 5000 rows.
