I want to calculate the overlap of specific column which may occur in multiple places.
Consider Person_Name as a column and I want to know in which location and country this Person_Name will occur and get the count of it.
I'm trying to achieve this under table visualization.
In that case you might want to use another feature ( I like it, I've mentioned it several times in Community so I hope I'm not too redundant ).
This is a bit of a grind, but I'm having trouble envisioning how else you'd display counts by country without having country as part of the report display ( rows or columns ).
If I'm still not getting it maybe post a sample wireframe or Excel example, but it certainly sounds doable.
