In my project I have Funtional groups field. In this field we have around 15 options. Based on this functional group, I want to restrict the issues which a particular group can view.
I will explain this with an example.
Suppose I have functional groups as a, b, c and d. I need to create a group who can view only issues related to functional group 'a', remaining issues this group should not be able to view.
Another group should be able to view only functional group 'b' and 'c' related issues.
How can I apply this filter or security in my Jira project?
