I'm attempting to open up connectivity between Qlik and SAP, this connection need to go through a SAP router to reach the destination message server.
I've been advised by our SAP guys that the required port for this connectivity to the SAP router need to go through a defined RFC port 3279, this differs to what I can see in the Qlik documentation (though the text around going through a router is limited).
If connecting through a router, would we still expect to have to open up the standard 32nn, 33nn or 36nn ports to the SAP router? Or just the port supplied to me?
Is there any specific return traffic on the expected port that the router would mirror? respond back on the expected 36nn for example
Anyone who has setup the connector in a similar manner please share some of your insights if possible
the SAP Router normally listens to port 3299. From the system running the Qlik SAP Connector you only need to open up for traffic to the SAP Router. From the SAP Router you need to open up for access to the backend SAP system on the relevant RFC port, 33XX.
thanks for the reply, is the 3299 a default listening port for all traffic?
I've been told we have two ports 3279 for RFC traffic and 3289 for GUI traffic, which would been needed for BEX connectivity, is traffic treated as GUI initially and then routing through to RFC? Or should it just be the RFC port?
What is the difference when the target is a message vs application server, should this still go to 33xx as you suggest or to 36xx for example when a message server?
I did some more testing with the combination of the BEX Connector and using a SAP Router to access a message server behind the SAP Router. There seems to be an issue when a message server is accessed via the SAP Router in the BEX Connector. For now I suggest you connect via the SAP Router to a specific application server rather than the message server. A fix for this issue will be included in a future release of the BEX Connector.
