About KeepAlive settings in S4HC

Hi Exparts,

Are the validity and validity period of KeepAlive published on the web server of the API destination in S4HC?
API destination:https://myXXXXXX-api.s4hana.cloud.sap

Best Regards,

Hi Kyosuke,

I think your question is more about session management and timeouts - is it correct?

Please be aware you should carefully manage your session usage, especially for high volume in an API scenario.

If you create new sessions with every call vs reuse/dispose of sessions, you will start to hit the upper limit of *unused* sessions (100 I believe, see the notes below) and you will not be able to create a new session until the unused ones are expired/cleaned up. Note that unused sessions are not the same as concurrent sessions that are in used. Unused ones are created, used once and then abandoned (i.e. not "logged off").

please see these notes for more information:

Please let us know if this doesn't answer your question
