You can view and edit parent records from the child record. For example, while on a Contact record, you can edit fields on the parent Account record.
- Make the inline edits (you will receive a notification).
- Prior to saving the data, the cell will have a blue mark (as opposed to the default red).
- Click Save Data. The parent record field will be updated.
This functionality is enabled by default. To disable, change the feature security for the Edit Parental Data field.
