Then it sounds like you looking to filter the report data by a parameter.
You can use ranges or add a filter. A filter works on the client side and operates on the flattened data. Filters must be used cautiously and must not be considered as an alternative for a query range because .the system fetches the whole data from the datasource, after which it then applies the filter/
The data needs to be restricted only to a certain data region and not the entire dataset.
A new parameter can be added to a dataset through a query.
When a dataset is linked to a query, then the parameters are automatically created from the fields that are added to the Ranges node in the AOT query.
e.g. on the filters node of the CustTransTable you might create a new filter and nn the new filter node, set the fproperties e.g.:
Name CustGroup
Value =1
Expression =IIF((Parameters!CustGroup.
Value=Fields!CustGroup.Value),1,0)
The data region displays only the data for which the expression evaluates to 1.
,Select preview and activate the parameters tab. The parameters that were added are visible along with the standard parameters. Verify the parameters through the report preview.
The deployed report dialog will provide a parameter field for CustGroup for you to enter a value.
If this does not make sense to then you need to buy a manual, or speak with a consultant.

It is possible to allow more parameters to be added by the user through the query framework. To enable this, set the Dynamic filters property to Yes on the datasource node
(You can also use a parameter that is not linked to the dataset but is needed for the purpose of reporting. Such parameters are referred as unbound parameters. These are parameters tare added manually and are typically used for the purpose of formatting or calculating methods.)
