I think what you would need to do is use the map's audit log in your error handling. The audit log contains the information you need. Most error handling withing the map itself doesn't work as designed, since the error can cause the error handling not to work.
If you are using a RUN map, you can pass the hard coded RUN map name to another card etc.
However, if you have the same map with different compiled names, this is inefficient. It would be better to use the RUN map's audit log to show what over rides were used. I would need to know more about what exactly you are trying to handle error-wise etc.
