3600044 - User session times out after 30 Minutes despite configuring SESSION_TIMEOUT_INTERVAL_IN_MINUTES - SAP S/4HANA Cloud Public Edition

Symptom

Users session times out after 30 minutes, showing "Session has timed out" error, even though SESSION_TIMEOUT_INTERVAL_IN_MINUTES was set to a higher value (e.g., 60).

Environment

SAP S/4HANA Cloud Public Edition

Reproducing the Issue

  1. Open the application 'Manage Launchpad Settings' and search for 'SESSION_TIMEOUT_INTERVAL_IN_MINUTES'.
  2. Click 'Edit' and sear for parameter SESSION_TIMEOUT_INTERVAL_IN_MINUTES and se it to 60.
  3. Open an application which is retrieving data (actively polling).
  4. Remain idle for 30 minutes.
  5. The ABAP session timeout will be triggered at 30 minutes and the session is not extended.

Cause

Backend Security Session (ABAP)

  • Has a fixed 30-minute idle timeout (cannot be changed).

  • Reset if any request reaches the server (polling).

Fiori Launchpad Polling

  • The Fiori Launchpad may send background polling requests (e.g., tiles, notifications).

  • Each polling request resets the 30-minute ABAP timeout, keeping the session alive.

  • Controlled by parameter SESSION_TIMEOUT_STOP_DATA_REFRESH:

    • If active, polling stops and the backend session expires after 30 minutes idle.

    • If inactive, polling continues and the backend session keeps resetting.

SESSION_TIMEOUT_INTERVAL_IN_MINUTES

  • Determines timeouts for stateless Fiori Launchpad sessions where no data retrieval is happening.

  • Does not override the backend ABAP session timeout (30 min) for apps that retrieve data.

Resolution

To prevent applications that have active polling from extending sessions, configure SESSION_TIMEOUT_STOP_DATA_REFRESH:

  1. Open 'Manage Launchpad Settings'.
  2. Search for SESSION_TIMEOUT_STOP_DATA_REFRESH.
  3. Click 'Edit' and input value.

Timeout = (SESSION_TIMEOUT_STOP_DATA_REFRESH value + 30 minutes).
