Cognos - Creating a Report
You can create a new report by inserting objects from the data source in the Query Studio. You can also change an existing report and save it with different name.
You can open Query Studio by going to Query my data option on the home page or you can go to Launch → Query Studio.
In the next screen, you will be prompted to select a package to add objects in the reports. You can select a recently used package or any other package created in the Framework Manager.
You can see Query items listed on the left side. You can add data and save the report.
