ERP –> HCI –> C4C: Does an On-Premise application need a public registered domain name

[fabian_otto]

Hi Experts,

let’s assume the following:

• An On-Premise application, e.g. ERP, is sending a request to the SAP Cloud, e.g. HCI.
• For the outbound communication a forward proxy is used.
• The On-Premise application does not have a registered domain name. It is an internal name which cannot be used for registration as a domain name.
• But there is a public domain, e.g. external.company.com which is registrated as an official public domain name.

Is there a need that the ERP system has a public registered domain name?

Please also refer to the following document…

So far as I understood it would be sufficient to use the public domain, e.g. external.company.com, for the certificate signing request.

Hello Fabian,

yes, it would be sufficient to use the public domain, e.g. external.company.com, for the certificate signing request.

Hello Fabian,

Only the target systems needs to have a public domain name.

In your case the target system is HCI so ERP does not need to have a public domain name.

If you plan to send data from C4C to ERP in that case you will need to use a public domain name like your external.company.com (and an SSL certificate from a CA trusted by SAP).

For security purposes SAP recommends to use a reverseproxy in order to prevent your ERP system to be exposed directly to the internet.
