Can users have their own subscription in SSRS?

Question

Is there a way user can subscribe a report of his own in SSRS 2008R2?
We have about 20 reports and 400 users and everyone have their report parameter selection criteria. Is there a way they can default their parameter selection and subscribe?
Another requirement is
Is there a way to save favorite selections within a report to then choose them later. 
Favorite #1
Favorite #2
Thanks,
Jo

Hi Jyo1105,
Answer1: According to your description, there are 20 reports and 400 users, you want to set specific parameter values based on recipients. If that is the case, we can achieve your goal by using Data-driven Subscription.
Reporting Services provides data-driven subscriptions so that you can customize the distribution of a report based on dynamic subscriber data. Data-driven subscriptions use query results to determine the recipients of the subscription, delivery settings,
and report parameter values. At run time, the report server runs a query to get values used for subscription settings. We can use the Create Data-driven Subscription pages to define the query and assign query values to subscription settings. For detail information,
please refer to the following steps:
1. Open Report Manager, and locate the report for which you want to create a data-driven subscription.
2. Hover over the report, and click the drop-down arrow.
3. In the drop-down menu, click Manage. This opens the General properties page for the report.
4. Select the Subscriptions tab, and then click New Data-driven Subscription.
5. Select the delivery extension and data source for the subscription.
6. Specify a query that retrieves subscriber data like below:
CREATE TABLE Name (
Group varchar(20),
Country varchar(20),
Type varchar(20),
Email_to varchar(50)
INSERT INTO Name
('Group1', ’Country1’, ’Type1’, '[email protected]'),
('Group2', ’Country2’, ‘Type2’, '[email protected]'),
('Group3',’Country3’, ’Type3’, '[email protected]')
7. Specify delivery extension options like below:
8. Specify report parameters for the subscription like below:
9.  Specify when the subscription is processed, then click Finish to save the configuration.

Answer2: As per my understanding, there may be several parameters in the report, when users preview the report, they need to select values for each parameter. So you want to save some selections as favorite.
In Reporting Services, we could not achieve the goal directly. As a workaround, we can use snapshot. For more details, please refer to the following steps:
1. Open Report Manager, and navigate to the report.
2. Hover over the report, and click the drop-down arrow.
3. In the drop-down menu, click Manage.
4. Click Parameter in the left pane, set default values for the parameters, then click Apply.
5. Click Report History in the left pane, click New Snapshot.
In this way, the parameter selections are saved, when we click the snapshot, the report server retrieves the stored report from the report server database, and shows the data, parameter selections and layout at the time when the snapshot was created.
If you have any more questions, please feel free to ask.
