Once a report is uploaded to Reporting Services, it may need some modifications on configurations in order to make the report available for end users. It can be related to data sources, security or even parameter values. One reason for these modifications could be, the environment used for development. During development, you may use different databases in different servers as data sources for the report. You may set testing values as default values for parameters. But they need to be changed once it is deployed to a different environment, generally to production environment. This is why we need to manage reports once they are uploaded.
We can use the Reporting Services Web Portal for managing the reports. It is easier to manage reports using the portal rather than changing configurations either manually or using another editor. Let's see how a report can be managed using the portal by reviewing and changing few configurations.
