External access to FLP

Hello Experts,

we have implemented a new FLP on S/4 which is reachable over the LAN as like:


Now i would map these with an external adress to like:


Do i just need to involve our network administrators to do so or are those mappings including work on SAP-side?

Hope you can provide me with some informations.

Best regards,

    Hello Volkan,

    I believe it depends on what kind of Fiori apps are in use.

    If you have webdynpro apps, or apps that launch a transaction at the S/4, then Fiori needs a system alias which will be used to generate the URL for the app. In this case, having two entry points would not be possible, or would require a lot of extra work.

    If you can make your internal users access Fiori using the external host as well, then everything is simpler :-).

    Your network team enables the external access using "MyExternalHost", they also make the external host work within the LAN, and then you just need to adjust the SM59 destinations related to Fiori to point to the external host instead of the internal one.

    • Hello Volkan,

      You are welcome :).

      The easiest solution would be for your infrastructure / network team(s) to make the external link to work at the internal network too (make the internal DNS servers respond with the internal IP address when the external address is queried).

      After that, adjust the references at the Fiori frontend system (these would be HTTP destinations of type "H" at the transaction SM59). Make all references go through the external link.
