Hi manikantan,
Based on my understanding, you create a drill through action in a main report, and you also specify a parameter to run the drill through report in Action properties. After drilling through to the target report, you want to select different values from the
drop-down list of the parameter to filter data, though the parameter has been passed from the main report, right?
In Reporting Services, if we have specified parameters for the drill through report in a main repot, after drill through to the target report, the report is already filtered. At that moment, we can’t select the parameter values from drop-down list to filter
drill through report. In a word, if we pass parameters from main report to drill through report, we are not able to filter report by selecting parameter values in a drill through report.
In your scenario, if you want to filter drill through report after drill through action occurs, please don’t specify parameters for the drill through report in Action properties. Then when you drill through to the target report, you can select parameter
values to filter data.

Add a Drillthrough Action on a Report (Report Builder and SSRS)
If you have any question, please feel free to ask.
