SSRS Interview Questions And Answers Pdf

1. What is a Managed Report?
Answer: A Managed Report is characterized by detailed operational data or summarized management information that is gathered from a variety of data sources and formally organized into a central repository. Also known as Static Reports. Often, managed reports must conform to specified formatting standards. They are created by technical people.

2. What is Subreport?
Answer: A subreport is a report that displays another report inside the body of the main report. Conceptually, a subreport is similar to a frame in a Web page. It is used to embed a report within a report. Any report can be used as a subreport. The subreport can use different data sources than the main report. The report that the subreport displays is stored on a report server, usually in the same folder as the parent report. You can set up the parent report to pass parameters to the subreport.
Although a subreport can be repeated within data regions using a parameter to filter data in each instance of the subreport, subreports are typically used with the main report as a briefing book or as a container for a collection of related reports. For reports with many instances of subreports, consider using drillthrough reports instead.

19.  What are ReportServer and ReportServerTempDB?
Answer: Reporting Services uses two SQL Server databases for storage by default, the databases are named ReportServer and ReportServerTempdb.
ReportServer is the main database, which stores all internal configuration and reports metadata whereas ReportServerTempdb is used to store temporary
data, session information, and cached reports.

20.  What are the different purposes of Roles?

22.  What are the drawbacks of reporting in SSRS?
Answer: For many years, Microsoft had no direct solution for reporting with the SQL Server besides Crystal Reports. Now, they have SQL Server Reporting Services, but it does have several drawbacks. It is still complex to understand the complete functionality and structure of this new component, and many users are still relying on the reporting application they are more familiar with, which is Crystal Reports. Also, components in SSRS like Report Builder and Report Designer are meant for different users for different aspects of the reporting process, yet complete understanding and exposure to both is important to utilize both functions fully and extensively. There are also issues when exporting very large reports to Microsoft Excel, as it can lead to a loss of data. (E learning Portal)

23.  How does Report Builder support Analysis Services cubes?
Answer: Report Builder supports relational SQL and Analysis Services data sources in SQL Server. To create a model for Analysis Services cube, go to Report Manager or Management Studio, create a data source for your Analysis Services database, and then select the Generate Model option to create the model.

24.  What are Click through Reports?
Answer: A click-through report is a report that displays related data from a report model when you click the interactive data contained within your model-based report. These reports are generated by the report server based on the information contained within the report model. The person who created the model determines which fields are interactive and which fields are returned when a click-through report is opened. These field settings cannot be changed in the report authoring tools. Click through reports are auto-generated. However, you can create an alternative customized report to the model for interactive data items that is displayed instead. The custom report is a standard Reporting Services report.

25. What is Data Set in report ?
Answer: Data set is a set of data that we want to show in the report. A data source is the source of data from where we are getting this data (database server name, database name, connection string).

26.  Are there issues when exporting SSRS reports into Microsoft Excel? When my users are trying to export an SSRS report into Microsoft Excel, one or two columns in the report appear to merge together. Why might this be?
Answer: Exporting from SSRS is not always perfect, even if you stay within the Microsoft range of products. If you have extra resources, you could splurge for an add-on that offers much better control over exporting to Excel, such as OfficeWriter. From my experience, though, it is usually headers or footers that cause exporting issues. If any of these headers or footers overlap with data columns in your report, you will find that the exported version of the report has merged cells. Also, check columns next to each other to make sure that there is no overlap, as well.

27. What are Linked Reports?
Answer: Linked reports are just shortcuts to a stored report. They allow a user to view the report without accessing the underlying folder or files.

28. What are the types of Subscriptions?

31. What are Report Caches?
Answer: If the report has to retrieve a large amount of data or multiple users are accessing the report frequently then a Report cache would increase its efficiency. Caching reduces the burden on the server’s resources. We use the cache report functionality to store the report execution in the cache for a desired period of time and all the user requests will be addressed by the Cache. You would use a cache when you are dealing with an excessive amount of data or there are multiple users accessing the files.

32. What is the Reporting Life Cycle?

50. What is Linked Report?
Answer: A linked report is a report server item that provides an access point to an existing report. Conceptually, it is similar to a program shortcut that you use to run a program or open a file.
A linked report is derived from an existing report and retains the original’s report definition. A linked report always inherits the report layout and data source properties of the original report. All other properties and settings can be different from those of the original report, including security, parameters, location, subscriptions, and schedules.
You can create a linked report on the report server when you want to create additional versions of an existing report. For example, you could use a single regional sales report to create region-specific reports for all of your sales territories.
Although linked reports are typically based on parameterized reports, a parameterized report is not required. You can create linked reports whenever you want to deploy an existing report with different settings.
