How To Fix BCOM_R079 - Download because address type &1 on server '&2' is unknown

SAP Error Message - Details

• Message type: E = Error

• Message class: BCOM_R - Business Communication: Messages for Rule-Based Routing

• Message number: 079

• Message text: Download because address type &1 on server '&2' is unknown

What causes this issue?

The scenario already exists on the server and the database version has
not been changed since the last download. The list of the address types
supported by the router (set in <DS:TRAN.SBCA>SAP routing server
administration</>) has, however, changed since the last download.
During a download, a routing server only ever receives the destinations
and business partner addresses, for example, that have an address type
that it also supports. If a new address type is added, the scenario and
the business partner addresses have to therefore be downloaded again so
that the scenario is current.
