I want to make a field editable for only 3 people. I have given edit access from profiel, The field is read-only on Page layout . is there a way I can make this editable on page layout for these 3 people without creating new page layout and new profile?
There are two ways to achieve this:
Keep the field editable on the Page Layout. Mark the field as
ReadOnlyat Profile Level. Next create a
Permission Setwith Edit Access on the desired field. Assign the
Permission Setonly to those three users.
Else, create a validation rule, which restricts edit for the field for all users except for those three users. Refer below example
AND(ISCHANGED(Field_To_Check__c), $Profile.Name < > "System Administrator", $User.UserName < > "User Name 1", $User.UserName < > "User Name 2", $User.UserName < > "User Name 3")
