Again, similarly to report variables, the variable name must begin with a letter, cannot contain spaces, and the name is case sensitive. A group variable can often be used in situations where you need to adjust a variable value per each group. Additionally, the variable is available for reference within any child of the group in which it is defined. Group variables differ from report variables in that their scope remains only within the context of the group in which it is defined. Group Variables in SQL Server Reporting Services For a variable that is defined as read-write, the exact time when aВ variable calculation is evaluated is not defined, so care must be taken in utilizing the write driven variables. Thinking through the different scenarios, you can easily see that setting the value once could be helpful on a long running report where maybe the exact time the report is run (and used in a calculation) is very important. Additionally, report variables are by default read only however, this behavior can be changed to read-write. First, the variable must begin with a letter and cannot contain any spaces furthermore, the name used is case sensitive. Of course as with any item, a few restrictions do exist in the use of variables. The calculations in the variable are made just once and then applied throughout the report, as they are used during that report session. Often, a variable is implemented when a value or calculation is used many times, but we want use a consistent value for each calculation. Report variables can be helpful when making complex calculations and are evaluated, often just once, at run time. SQL Server Reporting Services Report Variables

In this third tip, we will explore how to define a variable, at the group or report level, which can be referenced within expressions that are placed on a report. In the second tip, I covered building a Custom Assembly, a DLL, which can be referenced by a group of reports.
