How can I dynamically implement section access based on region and country fields

[Krishna_Chaitanya]

How can I dynamically implement section access across specifically using two linked  fields like region and country to avoid manually listing every country entry? 

Thanks.

The section access information mustn't be mandatory applied manually else any kind of script could be used to create an appropriate table. In your case you might be consider a cartesian join with a following filtering, maybe something like:

t1: load Country & '|' & Region as Key from Countries;
     join(t1) load User from Users;

t2: load * resident t1 where ....;
