Fiori Apps Keep Calling Internal Hostname / Internal FQDN
Had this issue where certain apps calls internal hostnames or internal FQDN when clicking or spawning webdynpro URL or any calling of internally hosted attachment.
To change this setting, general steps as below:
Check the app is using which local Alias - is it LOCAL or S4PS or S4FIn or whatever
Check in /UI2/V_ALIASMAP / /UI2/V_ALIASCAT that alis is mapped to which alias.
Check in SM59 under HTTP Connections to ABAP System
if let say the Alias name is LOCAL, so there should be three LOCAL_xx created, which are:
SO change for each of this, to the correct FQDN or hostname
Hope this helps someone.
