You can use Reporting Services aggregate functions that accept the parameter Recursive to calculate summary data for a recursive hierarchy. The following functions accept Recursive as a parameter: Sum, Avg, Count, CountDistinct, CountRows, Max, Min, StDev, StDevP, Sum, Var, and VarP.isplaying hierarchical data is a common use for recursive hierarchy groups, for example, employees in an organizational chart. The dataset includes a list of employees and the managers, where the manager names also appear in the list of employees.
You can change the report parameter properties in the report design tools to include a valid values list and a user prompt that displays at run time. You can also create cascading parameters, which retrieve hierarchical data from a data source.f the report parameter is tied to a query parameter and you do not use an available values list, it is possible for a report user to type SQL syntax into the text box, potentially opening the report and your server to a SQL injection attack.
