Fields settings from Custom field and context
By adding one or more context settings for a custom field you can configure the EDIT/VIEW rights for more than one project
Navigate to: Settings menu → “Issues” → “Custom Fields” → On your Protected Field → Dotted menu → Choose “Contexts and default values” → When page loads → Click “Edit custom field config”
On the custom field config edit page you will be able to set up the EDIT/VIEW permissions for the entire custom field context.
See Fields settings from Project on details on how the different settings work.
Note:
Any project specific settings for a protected field will override the context settings.
Un encrypted protected fields cannot have view permissions as they are viewable through exports and or the API.
