If you, like me, prefer darker themes in every app you use, you may want to use the “SAP Belize Deep” theme in the SAP Fiori Launchpad.
Unfortunatelly in the ABAP 1909 Developer Edition there’s an SICF Service missing (at least in my installation), which prevents you from changing the theme. This will be corrected in the next version of the Developer Edition (ping Ralf Henning 😉 )
Currently the “Appearance” isn’t loading:
In the meantime you can easily add the missing service:
In SICF add the service “interop” under path /sap/opu/odata/ui2 with the handler class /IWFND/CL_SODATA_HTTP_HANDLER
Don’t forget to activate the service
After reloading the Fiori Launchpad you can now choose the theme “SAP Belize Deep”.
