Answer: “Sorting” applies to the entire dataset, while “Interactive Sorting” allows users to dynamically change the sorting order on rendered reports. Interactive sorting is set on report items like columns or rows, enabling user control.


93. How can you implement a multi-value parameter in an SSRS report?

Answer: To implement a multi-value parameter:

  1. Parameter Properties: Configure the parameter to allow multiple values.
  2. Dataset Filtering: Use the “IN” operator to filter data based on parameter values.
  3. Expression Usage: Utilize expressions to handle parameter values within the report.

Multi-value parameters enhance user filtering flexibility.


94. What is the purpose of the “Data Source” in SSRS?

Answer: A data source in SSRS defines the connection to the underlying data repository, such as a database. It includes connection details like server, database, and authentication credentials. Reports are built using datasets that use data sources to retrieve data.


95. How can you implement drillthrough actions in an SSRS report?

Answer: To implement drillthrough actions:

  1. Textbox Action: Create a textbox or data item as the drillthrough link.
  2. Action Properties: Set the “Go to report” action.
  3. Configure Parameters: Define parameters to pass from the source to the target report.

Drillthrough actions facilitate navigation to detailed reports.


96. Explain the purpose of the “Subreport” item in SSRS.

Answer: A subreport is a report item that embeds another report within the main report. It’s useful for presenting related information or including multiple reports in a single layout. Subreports can have their own datasets and parameters, providing modularity.


97. How can you create custom code in an SSRS report?

Answer: To create custom code:

  1. Report Properties: Open the report properties.
  2. Code Tab: Navigate to the “Code” tab.
  3. Write Code: Write custom code in the provided textbox.

Custom code extends SSRS functionality using VB.NET or C#.


98. Explain the purpose of the “Document Map” in an SSRS report.

Answer: The Document Map provides a navigation pane in rendered reports. It displays a hierarchical table of contents based on report items’ structure. Users can click on items in the Document Map to jump to relevant sections in the report.


99. How can you implement a dynamic parameter in an SSRS report?

Answer: To implement a dynamic parameter:

  1. Available Values: Set the parameter’s available values using a dataset.
  2. Default Values: Use another dataset to define default values.
  3. Cascading Parameters: Chain parameters for dynamic filtering.

Dynamic parameters enable user-driven filtering and data selection.


100. How can you schedule report execution in SSRS?

Answer: To schedule report execution:

  1. Report Subscription: Create a report subscription.
  2. Delivery Options: Define delivery settings like format and destination.
  3. Schedule: Set the schedule for report execution.

Scheduled reports are generated and delivered automatically.
