Activate the Report Server File Sync Feature in SharePoint Central Administration
The Reporting Services Report Server File Sync feature utilizes SharePoint event handlers to synchronize the report server catalog with items in document libraries. This feature is beneficial when users frequently upload published report items directly to SharePoint document libraries. If the file Sync feature is not activated, content will still be synchronized but not as frequently.
The File Sync feature can be activated in SharePoint Site Administration after you install the SQL Server 2012 Reporting Services (SSRS) Add-in for SharePoint products.
This feature can be manually activated and deactivated per site but not at the site collection level.
The Reporting Services Add-in for SharePoint must be installed. If the add-in is not installed the file sync feature will not be visible in the site feature list.
To verify installation, view the list of installed applications in Microsoft Windows Control Panel. If the Reporting Services Add-in is installed, follow the instructions in this topic to activate the report server file sync feature.
To activate or deactivate the Reporting Services File Sync feature on a Site
From the main page of your site, click the Site Actions menu and click Site Settings..
In the Site Actions click Manage Site Features.
Find Report Server File Sync in the list.
To deactivate the Report Server file sync feature, you can use the same procedure but click Deactivate.
