2747065 - Unable to simultaneously work on two instances from the same data center - SuccessFactors Platform


  • Unable to work at the same time on two instances that are hosted on the same data center/stack
  • Unable to switch browser sessions between two SuccessFactors instances

Reproducing the Issue

  1. Access one of your instances (e.g.
  2. On the same browser, access a second instance (e.g.
  3. Notice that you are either:
    • Logged out of the first instance
    • The session is overwritten by the second instance


SAP SuccessFactors does not support simultaneous access to environments that are hosted on the same data center/stack, as per the example mentioned above.


For you to work on both at the same time and without conflicts, you will need to use two different browsers and/or the incognito mode. Alternatively, you can also use any other environments registered for your company that are hosted under different data center/stack and, therefore, can be accessed simultaneously.

A warning message has been introduced for this scenario. It will be displayed to the end user when they have multiple sessions open in the same data center from the same browser.

Important Note: The login across multiple SuccessFactors instances in same data center in same browser, without clean log out by the end user, might appear to function as expected while using IDP-Initiated logon URLs from some IDPs (like IAS, for example). However, this can still cause session intermixing issues between the instances, and is strictly not recommended.
