Take data from a dataset to run a stored procedure that is going to provide me data to populate a map

Hi everyone,

there is something I don't know how to do it. I have a dataset that provides data to a report and some controls.

I have another report with a map. I would like to take the data of the previous dataset that the user has selected (year, region, ...). I would like to take some of this data as parameter to run a stored procedure that is going to provide me polygons to populate the map.

Any idea how to get it?

Thanks,
