Just like it is possible to import templates, you can also import RCM data from other equipment. The RCM tabs all have an Import from Equipment button as well. Functionally importing from an equipment is the same as importing from a template.
However, unlike the import from template popup, this equipment import popup has no grid where you can see the equipment previously imported. But using the source fields you can still identify the equipment from which data was imported on both the RCM tab and the RCM Failure Mitigation tab of the equipment and the RCM Templates screens.
