Getting reference of an external local object.

Hello,

Is there a way you can use the class definition/implementation of a local class, from a different program? For example, you have function group A, which has class CLASS1 defined. From function group B, I want to be able to be able to use this same class definition.

Copying the local class to a global one is not an option in my scenario, because it is an SAP local class that I want to use and want to prevent any future complications since it would be used in a critical user-exit.

Any help appreciated.
