CORS error while trying to setup Live connection between SAC and EWM (S4 HANA)

Hi Team,

We are trying to configure CORS live connection between SAC and EWM (S4HANA) .

We are getting Error access to XMLHttpRequest at 'https://<target-S4HANA>:44300/sap/bw/ina/GetServerInfo?sap-client=100' from origin ' https:<source-SAC> has been blocked by CORS policy:

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

We have followed 2889975 - SAP BusinessObjects Live Data Connect and Google Chrome 80: connection failure and set parameter on server side as below.

Server-side solution

The server-side solution reverts to the previous behavior by explicitly setting the SameSite=None and Secure attribute to all cookies issued by the SAP system. This solution has different advantages:

Kindly advise if you have seen and resolved a similar issue.

Also note following supporting information:

1. Target portal is accessible in browser --- 'https://<target-S4HANA>:44300/sap/bw/ina/GetServerInfo?sap-client=100'

2. Browser version is Chrome Version 108.0.5359.125 (Official Build) (64-bit)

3. S4HANA kernel version. - SAP Kernal 785

4. CORS was configured using UCONCOCKPIT

We have followed below steps to configure CORS using UCONCOCKPIT as per the blog https://blogs.sap.com/2019/06/26/s4hana-connection-with-sac-sap-analytics-cloud-using-cors/

Add SAP Analytics Cloud (SAC) to the HTTP whitelist.

Looking forward to response on this.

Thanks
