Some or all of this information may be incorrect.
Check the values by using <DS:TRAN.SM30>Extended Table Maintenance</>
to view the content of table CRMC_EXT_SERVER.
The RFC Gateway requires a translation table which translates the RFC
interfaces and data structures into the COM interfaces and data
