Hi Ben,
External Object is used for interacting with legacy windows applications with no API. Applications which do provide an API may well be more suitably automated using a COM business object.
Any COM object can be called from a Blue Prism process, provided it implements the required interface. If your COM object of interest does not implement this interface, then you may wish to create a wrapper for it, and expose the wrapper as a COM object. Any such COM object must be registered in System Manager before it can be used from within a process. This is only recommended if you have an existing COM object to wrap; this is what the Objects > External system tab is used for.
External business objects are there for legacy purposes only and should not be considered for any new development.
