Required Permissions Depends on the item type:

- DataSource: ReadProperties
- Model: ReadProperties

Pass the DataSetDefinition object that is returned by the PrepareQuery method as input to the CreateDataDrivenSubscription and SetDataDrivenSubscriptionProperties methods.

The delivery query returns a set of fields that can be mapped to report parameter values and delivery extension settings for data-driven subscriptions. Each row in the result set contains values for a single recipient, such as an e-mail address to which the report is delivered.

The delivery query must be valid for one of the data processing extensions that are installed on the report server. For more information, see Data Processing Extensions Overview.
