How to provide Read and write access to operators based on country's information loaded in a custom schema.
I have a custom Schema in which we have Country as a column. This schema holds data cdr's from Portugal and Germany. Now i want to give read and write access to the data corresponding to the operator which belong to that country.
For eg :- operator's from Portugal can have Read access to the data corresponding to portugal country only and operator's from Germany can have Read/write access to the data corresponding to Germany country only.
