[Forum FAQ] How do I export each group data to separated Excel files in Reporting Services?

Question

Introduction
There is a scenario that a report grouped by one field for some reasons, then the users want to export each group data to separated Excel files. By default, we can directly export only one file at a time on report server. Is there a way that we can split
the report based on the group, then export each report to Excel file?
Solution
To achieve this requirement, we can add a parameter with the group values to filter the report based on the group, then create a data-driven subscription for the report which get File name and parameter from the group values.
In the report, create a parameter named Name which use the Name field as Available Values (supposing the group grouped on Name field).
Add a filter as below in the corresponding tablix:
Expression: [Name]
Operator: =
Value: [@Name]
Deploy the report. Then create a data-driven subscription with Windows File Share delivery extension for the report in Report Manager.
During the data-driven subscription, in the step 3, specify a query that returns the Name field with the values as the group in the report.
In the step 4 (Specify delivery extension settings for Report Server FileShare), below “File name”option, select “Get the value from the database”, then select Name field.
Below ‘Render Format’ option, select Excel as the static value.
In the step 5, we can configure parameter Name “Get the value from the database”, then select Name field. 
Then specify the subscription execute only one time.

Thanks,
Is this a supported scenario, or does it use unsupported features?
For example, can we call exec [ReportServer].dbo.AddEvent @EventType='TimedSubscription', @EventData='b64ce7ec-d598-45cd-bbc2-ea202e0c129d'
in a supported way?
Thanks! Josh
