I am new to Salesforce and Salesforce development, and I have an object (Ticket) that is related to another object (Well) via a lookup field for the well ID. I want to pass that well ID to a custom field I have created called WellTicketID. Essentially, I want to populate the WellTicketID field with the lookup field value in the same object without any action required on the user's part. Any help with this would be greatly appreciated. Thank you!
