Functions in SSRS:
In Reporting Services, expressions are used to provide dynamic flexibility for controlling the content and appearance of a report. Some expressions are created for you automatically. For example, when you create a new report and drag fields from datasets onto report items, the values of text boxes are automatically set to expressions that refer to the dataset fields by name. During report processing, each expression evaluates to a single value that replaces the expression when a report is rendered. Expressions are also used throughout the report definition to specify or calculate values for report item properties, text box properties, parameters, queries, bookmarks, document maps, filters, and group and sort definitions.
You create expressions on report items by entering text in text boxes, in properties, or through a dialog box. An expression is written in Microsoft Visual Basic. An expression begins with an equal sign (=) and consists of references to constants, operators, functions, and built-in report global collections including fields and parameters. You can also create references to .NET Framework classes, custom code, and assemblies external to report processing.
Executing Functions:
Steps to execute functions:
1. Left click any field in the report where functions are needed.
2. Click in the Expression as shown in the picture.
3. Write the functions as per required as shown in the picture.
