You can connect a Create Request (CR) to an engineering part revision. By doing this, you have easy access to the CR from the engineering part revision. By using Attachments from the engineering part revision, the Change Request tab will be available, showing some CR information. From there you can use the zoom functionality.
It is also possible to create the CR via an engineering part revision, and thereby automatically create a connection between the CR and engineering part revision. For more information on this, see the Register CR activity.
