I found out (and I’m not the only one), that if the gateway creates an interface, which shows up in SEGW under Runtime Artifacts and you delete it in the class builder (right-mouse click via ‘Go to ABAP Workbench’ from SEGW), it STILL shows up under Runtime Artifacts and you can’t get rid of it.
That’s not good because it can pile up junk during project development.
Here now, until this bug is fixed, a brute-force work around for all sufferers:
The objects are located in database table /IWBEP/I_SBD_GA
I deleted the entry (I know, it’s not elegant, but it works for now) and SEGW is clean again:
And the best thing, if you do this in the development system, the changes will be effective in target systems after transport.
Nevertheless, SAP plz fix this bug 😉
