Drill Down With Tablix

Question

Hello, group -
I'm trying to figure out how to apply a drill down report tied to a cell entry in a Tablix. Now, I don't mean something that expands to see detail, like with a '+' button, but something that brings up a new report using its own query, when the contents
of a cell is clicked and that uses the clicked term as the criteria in the associated query.
What I have is a Tablix that looks like this;
Basically, it just uses a SQL query to show how many members belong to a particular doctor (PCP).
When the report is run and the table populated, what I want to do is to allow the user to click on the contents of the PCP Name cell;
and have SSRS run a second report that brings up a detail listing of each member's demographics; name, address, phone number, last visit, etc.
Is this possible?
Thanx in advance!

Hi Adam,
If you want to add the "Go to Report" action, and have an same field on both the main report and the subreport, you can use this field as the relationship field and create parameter based on this field on the subreport.
For example,"@PCP_NPI" is the parameter you have created on the subreport and you have also create filter on the subreport based on this parameter, and the field "PCP_NPI" exists on both the main report and the subreport.
If you want to add "Go to Report" action(Snapshot1 you have provided) and specify the report (sPCPMbrListDetail). You will not need to create an subreport again like in the snapshot2.
Thank you for the post, Vicki.
For the moment, until I get this down, I'll stick to basics and just have the main report call a subreport and not display it as part of the main report's tablix. Once I get a good handle on it, I'll explore the other option.
I have created a parameter, @PCP_NPI, in the subreport and assigned it a default value for debugging. The subreport works fine on it's own using the default parameter value.
I have the Tablix on the main report set to call the subreport when a PCP name is clicked, passing @PCP_NPI to it, as shown below;
When I run the main report and click on a PCP I get an error that reads;
"The report parameter 'PCP_NPI' is read-only and cannot be modified."
If I remove the parameter from the subreport, I get an error that reads;
The Value expression for the query parameter '@PCP_NPI' refers to a non-existing report parameter 'PCP_NPI.'"
I see this error as an expected one, since the parameter is not defined in the subreport any longer.
The problem seems to be that I am unable to modify the parameter from the main report; something is locking it, but I don't know what.
I'm afraid I'm at a complete loss here. It seems that I'm following the instructions given, but something I'm doing is wrong.
