I have few type of subject heading under Note, I would like some note can be edited by the manager beside the owner, for this I have set “group” right under the role management for the manager, how do I set if I want some of these note can only be edited by the owner only? I understand that I cannot set “Owner” role to the manager or else he will not be able to edit some notes.

SuiteCRM does not currently offer field-level security, so you cannot set display and edit permissions by field, by user. You would have to do this via some custom coding.

Thanks for your respond.
