Hi,
As already explained, there is no transaction code which will check the correctness of MM configuration. There are few checking transactions like OMGQCK, OMGSCK etc to check the release strategy.
The correctness can not be validated by the system, since the configuration changes from scenario to scenario and from client requirement to requirement. If you need to check the health check of the system, it has to be done by an expert MM consultant with the client specific business knowledge only!
