2890576 - After Google Chrome / Microsoft Edge browser updates, Live Data Connections are no longer working in SAP Analytics Cloud (SAC) & SAP Digital Boardroom

Symptom

After updating Google Chrome to version 80 and above, the following error occurs when using any Live Data Connection in SAP Analytics Cloud (SAC):

  • "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."
  • "Possible causes: Third-party cookies are blocked, or CORS is not configured correctly. For more information, see our troubleshooting page."

Environment

  • SAP Analytics Cloud (Enterprise)
  • Google Chrome version 80 and above
  • Microsoft Edge version 86 and above

Reproducing the Issue

  1. Log in to SAP Analytics Cloud.
  2. Open a story based on a Live Data Connection.

Cause

  • After the rollout of Google Chrome versions 80 and above, Google has activated stricter cookie handling for the SameSite attribute. By default, SAP Applications such as HANA, BW, BW/4HANA and S/4HANA do not set the SameSite attribute, so as a result, user authentication to live data connections to these data sources will fail, causing stories to also fail (unable to retrieve data) based on these live data connection types.

For more information, refer to the resources below:

Resolution

*Important* - If you are facing the issue after the update of Google Chrome and Microsoft Edge Release 91, the Browser Side Solution (Flag disable method) listed in the SAP Note 2887651 below is no longer available.

To solve the problem caused by the change of web browser behavior, the back-end systems need to set the following two cookie attributes for all cookies:

  • SameSite=None
  • Secure

For data source specific steps on how to set these cookie attributes, refer to the SAP Note 2887651 - Issues with SameSite cookie handling for the latest information.
