You can have a drillthrough action with parameters. First, specify the reportname that you want to drill through. then you can add parameters, in your case you need 2 parameters. On the Name : Specify the name of the parameter from the report that you are going to drill through. On the Value : Specify the fieldname that has the values that will populate your drill through report parameters (Branch & Category)
