The stored Proc. (sp) returns fields as follows:
CityID, cityName, citydate, population, area, counties, ...
The above fields are used to populate the data into a table control on the report.
Inside the report, there is a drilldown functionality on cityName so that at first the table is shown with the cityNames and plus sign next to them. When the cityNames are expanded, then the other above columns are shown.
Inside the sp, before the above result is returned, there is a table variable which holds the clientNames in each cityName. Note that these two tables can be linked via cityID.
As mentioned before, in the existing report, when you click on the plus sign, the above fields are shown i.e. cityName, citydate, population, etc...
Now, I would like to have another drilldown on one of the columns such as citydate so that when it is expanded, it shows the data inside the table variable i.e. CityNames.
Do you know what I should do please?
