How can I configure Issue-Level security with Epic Link

[Carlota Vendrell]

I want to configure an Issue-Level security where an user can see only tasks related to one Epic Link. How can I configure it? Thanks :)

Have a look at this answer to get a way to get what you need:

Note you may add a User Picker custom field instead of a Group Picker one.

For step 6, you may use parentEpic() function before the bulk change:

Hope it helps.

Could you elaborate more on what you mean by "user can only see tasks related to one Epic Link"

I have a project with three epic links (for example). I do not want to share this project to everyone, but I need that one person sees the tasks that are related to one of these three epics. Do you understand?
