Common Component Subtabs

Use the common component subtab to add either a Notes subtab or a Change History subtab.

The Notes subtab shows a list of notes related to a custom, top-level object. At runtime, users can access the Notes subtab and create a note that's tied to the current record. For example, a user can record a note on a service request record.

Tip: You can optionally modify the look of the Notes subtab from the Pages node under the Note object.

The Change History subtab shows a list of changes made to the current record. Users can see a record's change history without having to leave the record, which helps to reduce issue resolution time. You can enable this subtab for custom objects, and also for a set of standard objects.

To add a common component subtab to an existing details page:

1. When editing any custom details page layout, scroll down to the bottom of the existing subtabs.

   Click the Add icon.

2. Select Common component.

   Note: If the Common component option is disabled, then both the Notes and Change History subtabs already exist on this layout.

3. Select either the Notes or Change History check box.

   Note: If a check box is disabled, then that subtab already exists on this layout.

The Notes subtab isn't secured, so anyone can immediately view it at runtime.

The Change History subtab, however, is secured. If you add the Change History subtab to a standard object, make sure your users have the right privileges to view the new subtab. For custom objects, grant your users the privilege to view this new subtab by going to the custom object's security node. See "Manage Security by Object."
