    If your SSRS setup similar to the one below. You're likely running into a common SSRS Reporting Service Double Hop (aka Negotiate / SPNego / Kerberos/ SSO) issue.

    Clients e.g. PCs -> SQL Server A (Hop 1) with SSRS -> SQL Server B (Hop 2) contains DBs where your SSRS data sources are pointing to.

    There're 2 solutions to this. Solution 1 is to hardcode credential in each Data Source. Solution 2 is to configure Kerberos Authentication (SPN + Account Delegation). There 3 places need to be configured correctly in order for it to work properly. May be easier to watch the following video which explains things a bit better.

    1. SPN & Service Account Delegation on Domain Controller
    2. Authentication Type in SSRS Configuration File rsreportserver.config on the SSRS Server
    3. App/Script such as Browsers, Web Apps, Python, PowerShell, etc. Integrated Authentication Settings, Additional Modules, Add-ons, etc.

    There are other reports that has direct datasource connection and is able to run without any issues. But one of the stored procedure is using the linked server and output the error when running report. Added both report server user and datasource user to the security properties of the stored procedure. Also granted execute privilege to stored procedure of report server and datasource user.

    Can the stored procedure use linked server to connect to the server for generating report? If yes, what is the command to execute so it output the data

    Hi @Avyayah ，

    "NTAUTHORITY\ANONYMOUS LOGON" is the built in IIS account on your report server. The reports are being executed from this account which serves up the page to the user.

    Please update your Data Source to use "As the user viewing the report".

    You may also choose "Using the following credentials" to use stored credential.

    For more information:
