Is there any way to say that a user can only see records if a field is not null? I have an outside partner who wants access to our CRM, but we only want them to be able to see records that are "tagged" as theirs, by having a value in a field. It's not possible or plausible to change the owner of the records to this user, and their access need would cross between leads, opportunities and activities.
Just wondering if anyone had any thoughts on this? Is it even possible?
Thanks!
