Maps can act as filters just like any other chart in Qlik. So if you have a map chart and another chart showing details of all countries, you can click on USA or any location within it, to show the particular region's detail only. You have to make sure your data has that level of granularity. Not sure if you were looking for something else here.
Thanks for the quick response. You are right i am looking for the same feature but just wanted to know if we can replace the map with its details pivot table on selecting any value on the map, if not then is it possible to navigate and show the table in the next sheet.
