Can't see my Service in IWFND/MAINT_SERVICE

When trying to add my service, from my ED2(300) server, I can't see it in the Gateway IWFND/MAINT_SERVICE

It's definitely there in the backend, I've activated SEGW...

The way round this (for reasons unknown...) was to create a SEGW Project in the Gateway with the same name as the project in the backend. 
You don't need to populate it with the data entries, mappings to fms etc, just needs to be a faux shell.

Once that's done, go back into the IWFND/MAINT_SERVICE transaction, and try and add the Service again.

This time round, the Service was there, and the transaction even seems to have picked up that it needs to be looking at ED2(300). My guess as to why the latter should be the case is that this was a previously used service that was deleted then re-inserted.

Thanks a lot to Manu for this one... :D
