-The Report Viewer web part can be used to embed SQL Server Reporting Services native mode reports within your SharePoint site. This web part is available for SharePoint 2013 and SharePoint 2016.

+The Report Viewer web part is a custom web part that can be used to view SQL Server Reporting Services (native mode) reports within your SharePoint site. You can use the web part to view, navigate, print, and export reports on a report server. The Report Viewer web part is associated with report definition (.rdl) files that are processed by a SQL Server Reporting Services report server or a Power BI Report Server. This Report Viewer web part can’t be used with Power BI reports hosted in Power BI Report Server.

 1. Configure your Reporting Services (Native Mode) instance for Kerberos Authentication by determining the SSRS Service account, setting an SPN, and updating the rsreportserver.config file to use RSWindowsNegotiate Authentication Type.
