Hold on a second! How would you like to view this content?
Just the title! A brief blurb! Gimme everything!
  1. Do you know how to get maximum logging in Report Server?

    By default SSRS will track reporting execution for the last 60 days. This might be OK in most cases, but you may want to adjust the retention days if you want better report usage statistics.

    ​T​o update the value you can:

    1. ​​Connect to the ReportServer database in SQL Management Studio
    2. Execute the following script and update the value to the number of days you want to track

    ​​EXEC SetConfigurationInfo @Name=N'ExecutionLogDaysKept',@Value=N'365'

    After you have this, you can query the ExecutionLog table to find useful information about report execution like:

    • ​Which users are actively using the reports
    • How long reports are executing
    • The last time a report was executed

  2. Do you know which reports are being used?

    SSRS keeps track of each report that gets executed and records useful information like:
    • How long did the report take to generate
    • Who requested the report
    • When was the report generated
    • Report Parameters used
    So it's quite simply a matter of querying the ReportServer database for information in the ExecutionLog table. 

    ​WITH RankedReports
    (SELECT ReportID,
            RANK() OVER (PARTITION BY ReportID ORDER BY TimeStart DESC) AS iRank
       FROM dbo.ExecutionLog t1
            dbo.Catalog t2
              ON t1.ReportID = t2.ItemID
    SELECT t2.Name AS ReportName,
           MAX(t1.TimeStart) LastAccessed,
           SUBSTRING(t2.Path, 0, CHARINDEX('/', t2.Path, 2)) ParentFolder,
      FROM RankedReports t1
           dbo.Catalog t2
             ON t1.ReportID = t2.ItemID
     WHERE t1.iRank = 1
    GROUP BY t2.Name, Path, ReportID
    ORDER BY MAX(t1.TimeStart) DESC;

    ​​​The query above gives you the last reports that were accessed (Credit to Eric Phan - SSRS - Find out which reports are being used (handy for migrating only the useful reports to a new server)​)

  3. Do you know the 5 user experiences of Reporting Services: Vanilla, Website, Email, Windows and SharePoint

    ​The five user experiences of Reporting Services are:
    • Vanilla (Report Manager)
    • Website
    • Email
    • Windows
    • SharePoint​

  4. Do you know when to use Reporting Services?

    Like any solution, Reporting Services has its pros and cons. From our experience, we have discovered these things about Reporting Services:
    • Parameters - you are forced to use built-in controls
    • Query string - when you change the parameters and refresh a report, the values do not appear directly in the query string, making it hard to copy/paste URLs
    • Can't separate SQL into a strongly-typed dataset or middle-tier object like in ASP.NET
    • There are potential difficulties with the deployment of RS reports and the exposing of them. However, once we have the infrastructure...
    • You can develop read only reports faster in Reporting Services than ASP.NET
    • Maintenance with RS is easier than ASP .NET, as with most cases you don't have to write any code
    • Flexibility with groupings and totals is easier. In ASP.NET you would need to iterate through the DataSet, keeping variables with the totals
    • Parameters are built-in. In ASP.NET there is code
    • Drilldown interactivity. In ASP.NET you need to code up a treeview
    • Users can have reports automatically emailed to them on a schedule
    • Users can export natively to PDF and XLS, plus a variety of other popular formats
    So in conclusion, if you will only ever need 1 report, go with ASP.NET - it is easier to get up and running. If you plan to have more than one report, use Reporting Services - it's worth the time to configure.

  5. Do you know how to migrate reporting service reports

    ​​​​Figure: How to migrate SSRS reports from an old server to another

    Let's say you want to migrate SSRS reports​ from an old reporting service server (e.g., SQL Server 2008 R2) to a new one (e.g., SQL Server 2016). What involves?

    There are three steps:​

    Step 1: Find the reports that don't need to be migrated

    • You need to install SSW SQL Reporting Service Auditor both on the old and new servers. (You'll also need to run it on 3rd step)
    • Find those reports are not-in-use, as per a rule: Do you know which reports are being used?
    • Find creators of those reports, by clicking “Detail Views” in reports folder
      Figure: Find reports creators by clicking "Details View" inside report folder
    • Send an email to report creater ask for permission to delete 
       Figure:  Send an email to ask permission
      Figure: Email received with permission to delete from creator
    • 2. Migrate those in-use reports from old server to new server​

      Tip: use the ReportSync​ tool to save time

      3. Check audit results

      • Run SSW SQL Reporting Service Auditor on both sides
      • Compare audit results. Note that even error and warning messages also need to be the same

      If audit results are exactly the same on old and new servers, it indicates that migration is successful.​

  6. Do you use Report Server Project?

    ​When working with SSRS reports, you need to have the right type of project otherwise it will be difficult for a developer, to create new reports or update existing ones.

    If you have some reports and want to check them into source control, if you add them to project that is not a report project, your reports will not open in the design/preview view (allowing to see the DataSource and DataSets). They will open in the XML view (which is not pretty to work with).

    Figure: Bad example – C# project with reports opening as XML

    To open the reports in the right view you will need to:

    1. Be sure that you VS has the tool/extensions Microsoft Reporting Services Projects installed, go to Tools | Extensions and Updates | Online, and search for services
      Figure: Checking Microsoft Reporting Services Projects is installed
    2. Create the project selecting Business Intelligence | Reporting Services | Report Server Project
    3. Add existing reports and create your new DataSource (based in the information on your Report Portal)
      Figure: Good Example – Report Server project with reports opening in the design/preview view

  7. Do you verify that Report Server authentication settings allow a wide range of web browsers?

    ​​​​The default configuration for Report Server isn't accessible​ by most mobile browsers and some desktop browsers too. You can adjust the authentication types allowed to increase the range.

    ​The configuration file for the Report Server is named RSReportServer.config and the default location is C:\Program Files\Microsoft SQL Server\MSRS13.MSSQLSERVER\Reporting Services\ReportServer\

    You should make a backup of the configuration before editing it so you can rollback if you make a mistake.

    We normally change the AuthenticationTypes node from:

                                <RSWindowsNegotiate /> 
                                <RSWindowsNegotiate /> 
                                <RSWindowsKerberos /> 
                                <RSWindowsNTLM /> 

    Check out the different Authentication Types in the Report Server documentation ​ and select the types that suit your needs.
