Publishing Data Sources and Reports (SSRS)
Before publishing your report, you should preview the report to see how it will look when it is run. You can continue to refine the design until you are satisfied with the results.
After you design and test your report, you may want to share it with other individuals. To share your report, you need to publish, or deploy, it to a report server or SharePoint site. After it has been published, individuals who have permissions to the report server or the SharePoint site can run your report. In addition, a person with administrator permissions on the report server can create subscriptions to your report so that the report can be updated and sent to users on a regular schedule.
If you used a shared data source to create your report, you need to publish it to the same location as the report. Like reports, shared data sources can be managed separately on the report server.
