Linked Report in SSRS 2008

A linked report is derived from an existing report and retains the original's report definition. A linked report always inherits report layout and data source properties of the original report. All other properties and settings can be different from those of the original report, including security, parameters, location, subscriptions, and schedules.

You can create a linked report on the report server when you want to create additional versions of an existing report.

we have two report:
Orders - List of orders
OrderDetails - Order Details

we have the case study:
List Order will list all orders in database
in running, the user can click to orderid and OrderDetails will display the information of that order.

you do following the step:

Step 1:
-> Change the query to Select * From [Order Details] where OrderID=@OrderID
-> parameter @OrderID will be generated in Parameter category
-> You run this report alone, you have type orderid

Step 2
righ click orderID field
