Hi

(1) Add the parameter that you require for the subreport to the main report. To do this open the Field Explorer window, right click Parameter Fields and select new. If you are using a stored procedure for the subreport use the same name for the parameter as you have used in the stored procedure e.g. @De_ID; Also ensure that the datatype for the parameter is compatible with the stored procedure e.g. Use number if the stored procedure parameter type is int.

(2) Once you have added your parameter right click the subreport and select Change Subreport Links... This will open the Subreport Links window. Scroll down the Available Fields Treeview in the top left of the window. Under Report fields locate the parameter you added in step one. Select the parameter and press the > button. Click the "Subreport parameter field to use:" dropdownlist and select your parameter from the list. Press the OK button. Now the subreport should use whatever value is in the parameter you added to the main report in step 1.

(3) You can populate the value of a reports parameter programatically by doing the following.

Dim pv As Integer = 1 'Parameter value
Dim pn As String = "@De_ID" 'Parameter name
reportDoc.SetParameterValue(pn, pv)

 Note you have to setup the Report Document object before you add parameters to it. See code above.

Good luck.
