I need help with my Validation Rule. In my scenario, I have one Custom Object and in the Custom Object, I have one "Record Owner" Field which is lookup through the User Object. I want only that user edit that record which is assigned to him and that record "Read Only" for others. Also, I have Some Profiles, Those Profiles have access to all the records which is assigned or not. Here's my Validation Rule:- IF( OR( CONTAINS( $User.ProfileId , 'ID'), CONTAINS( $User.ProfileId , 'ID'), CONTAINS( $User.ProfileId , 'ID'), CONTAINS( Record_Owner__r.Alias , $User.Alias ) ), false, true ) From this Validation Rule, I got the error when the other Profile User trying to update that Record which has access for all the Records. Thank you in advance
