Parameters for Report Snapshots
Parameterized reports that run as report snapshots use the parameter values defined for the report snapshot. Parameter values are defined in the parameter properties page of the report. Your subscription cannot override a parameter value that is defined for a snapshot. For example, suppose you are subscribing to a Western regional sales report that runs as a report snapshot, and the snapshot specifies Western as a regional parameter value. In this case, if you create a subscription to this report, you must use the parameter value Western in your subscription.
To provide a visual indication that the parameter is ignored, the parameter fields on the subscription page are set to read-only fields.
If you change a parameter value in the report snapshot after the subscription is defined, the report server deactivates the subscription. Deactivating the subscription indicates that the report has been modified. To activate the subscription, open and then save the subscription.
