Hi Kranti,

Outbound communication from SAP ERP (ECC, S/4HANA) usually is not considered to be exposing ERP to internet threats because the call is initiated within the network.

But if this is a concern, you can use a third-party on-premise application as a proxy (or a proxy) to get internet access. Alternatively, you can request an exception to allow outbound-only connectivity from ERP to SAP BTP as your middleware, in this case, share the IP range for your tenant with network/security.

Hi Kranti,

ECC can use HTTP Proxy to connect with CPI.

As Piotr there are outbound protocol for ECC to use, you need know which approach applicable to your scenario. For IDOCs, you can check this. Search for the others wouldn't hurt.

In Destination, there is an option to use proxy. For Proxy server settings, Infra/Basis team can help.

Dear Piotr,

thanks for reply ,

in our scenario ecc should not expose to outer world due to security .

You shouldn't need to expose the system to the public internet to invoke an HTTPS call to CPI.

I dont know if i understand, but you need a Cloud Connector configuration to connect on premise with cloud BTP.
Did you do know something like that ?

Dear Higor,

We can use cloud connector to connect sap cpi to on premise sap it means ecc inbound calls .

Cpi->cc->onpremise ecc

But there is no option in cc for outbound calls to connect to cpi.

Onpremise ecc ->cpi.

Kranti.

Usually any outbound protocol from ECC can call CPI through HTTPS, you can use SOAP, REST, IDocs.

Do you mean SAP don't have outbound connection outside of internal network?

If yes, then you simply can't connect with CPI.
