Limit ability to edit record based on user name
I have this Quoting database layout with 5 tabs, 6 portals and oodles of fields. My quoters have asked me if it's possible to allow all quoters to have read access to any record but to only be able to write to records that they have created.
I know I can do this with 2 layouts but would rather not have to maintain two of these ginormous layouts. I use external authentication. Thoughts?
