Hidden – parameter is not presented to end users when running the report, but the parameter can be passed into the report at run time and does show up when setting up subscriptions. Internal – similar to hidden except in addition to not being presented to users running the report, it cannot be passed in a run time.

Internal Parameters in SSRS are parameters that are not configurable by the end-user at run-time.

This varies from a Hidden Parameter, which the user is not prompted to provide, but can still be configured through the URL to the report server.

Please see "Creating Report Parameters" on MSDN for more information.

One possible usage of them is in conjunction with the Report Viewer control. An ASP.Net page can contain the report viewer control, and use internal parameters in the code-behind to provide values to the report that the end-user should not be able to control, such as a UserID.

This can prevent the user from providing a different user's ID in order to see data that they shouldn't be allowed to view.

However, if you use an internal parameter in a report but want it to remain functional outside of the report viewer control, you'll want to specify an appropriate default value. Otherwise the report will be unusable from the Report Manager or Report Server.
