Key information:

• Communication between SAP (Connector) and message broker relies on SOAP based web services

  • the communication between them is bidirectional

• There is one web service running by a message broker that SAP is connecting to

  • TCP port used by message broker is defined in its config

• There is one web service running by SAP that message broker is connecting to

  • TCP port used by SAP is configured systemwide (check t-codes SMICM and RZ10)

• If there is a firewall between SAP system and message broker a communication in both direction must be assured respecting used ports on both sides. More on the use of firewall you will find here.

• Use of secure connection is optional. Both channels, to and from message broker can use HTTPS independently from each other

• Communication between message broker and FSM cloud is

  • always unidirectional from message broker to FSM - FSM never initiates connections to a message broker

  • always secure, HTTPS based

• If there is a firewall between Message Broker and FSM cloud its settings must follow guidelines described here.
