Have a look in your documentation, if your system interfaces are not documented, then something is wrong in your place... But on the other hand, you could check RSA1 for datasources, SM59 for remote connections or WE20 for connected logical systems. Be aware that severe damage can be caused be unknowingly changing things in these transactions!
Good luck, Michael
