The most valuable feature of the solution stems from the fact that it is a properly working solution. My company has a support partner in Stockholm who has built several additional applications on IBM Cognos Controller. The functionalities and package offered by the product seem to be the right fit for our company.

The most valuable feature is that you can bifurcate or clear reports. This is on the date ranges. 

If there's already a scheduled report and we want a subset of that report, that can also be created. So we do not have to schedule a new report or create a new subscription for that. At this rate, we can create a subset out of one report itself.
