Cloud Platform Integration Connections Inbound from On-Premise ECC

We are currently on a CPI Trial for a Proof of Concept and we can connect outbound from CPI to ECC via Cloud Connector.

Our issue is Inbound connections to CPI from ECC as our ECC systems cannot be exposed outside our network. This means no SOAP connections and no reverse proxies.

We have been reading a lot to see whether we can connect back to CPI via Cloud Connector, but we haven't been able to find any documentation describing that scenario.

Works: SF -> CPI -> SCC ->ECC

Not working: ECC -> ??? -> CPI -> SF

We understand that it may be possible to do ECC -> PO -> CPI -> SF, but again no documentation describing this scenario.

Has anyone done anything along these lines that could point us in the right direction?

Hi Mathys,

Usually all customers use a PROXY server to route the traffic from ECC/S4 to CPI.If you have a web-dispatcher installed , you may use the Proxy feature of the web-dispatcher as well to do this proxy functionality, i know some customers doing this.

Hi Harish, Is my understanding correct? - If we implement Web dispatcher and use the Cloud connector in SAP Cloud Platform, we will not need PO to integrate with our Non SAP cloud apps? We have an older version of ECC (ERP6,EHP3) with no immediate plan to upgrade. Everything is routed through PO currently, so we are checking whether SCP can take on some of that load.

I'm a P user, cannot access notes.

hi mathys_vandermerwe,

If I understood correctly you are trying to access CPI from ECC system. So technically you are not exposing ECC to outside network, instead you are trying to consume a service or send a request to CPI URL which is over internet.

So if its SOAP based service you could use SOAMANAGER to create a logical port and provide CPI URL to connect to service.

In case your network doesnt allow even to connect and serivce over Internet you could use the second approach as mentioned by you.

ECC -> PO -> CPI -> SF.

You could use HTTP receiver adapter and on CPI sender you could have HTTPS adapter. But again your PO system should be allowed to connect to the service exposed by CPI which would be over internet.

so your scenario would look like below.

ECC --> PO -->[HTTP/SOAP/REST] --> [HTTPS/SOAP/ODATA]-->CPI --> SF.

Hope this helps !

thanks and regards,

Hi Praveen,

Yes, unfortunately we cannot connect to any external service from our ECC system. All external connections are via PO and soon also an additional AAE as that removes the backend systems further from direct connections.

I will give your information to our PO consultant and update on progress.

Thanks for helping.
