BizTalk: Use SAP Adapter to connect SAP message server

  • Article

When you use Microsoft BizTalk Adapter v2.0 for mySAP Business Suite SP1, there is a way for you to send messages to a SAP message server so that load balancing can be archived.

The send port setting is pretty straight forward; but there are some points to keep in mind.

  1. Make sure you do not specify System under Application Server. Client needs to be specified.
  2. Specify Group, Message Server, R3 Name under Message Server.
  3. When you try to send a message to SAP, it may fail and you may receive this error in SAP RFC trace:

         ERROR       service 'sapmsXXX' unknown

This message indicates the BizTalk Server does not know which port to use to connect to the SAP message server. You shall add an entry about its port number into x:\Windows\system32\drivers\etc\Services file. Your SAP admin shall know the exact port number.
