No System Alias found for Service 'ADT_0001' and user 'DEVELOPER' on demo system

[abo]

Using AS ABAP 7.52 SP04, Developer Edition I wanted to try settting up ABAP Development in VS Code

First step is checking that ADT_SRV works but I get this error message:

No System Alias found for Service 'ADT_0001' and user 'DEVELOPER'

It mentions transaction /IWFND/ERROR_LOG which also doesn't work: "User no longer logged on". I've tried with both the Java SAPGUI and the classic Windows version, no luck. Same answer to /IWFND/MAINT_SERVICE

How can I get this to work?

I'm especially interested in the experience of those running the developer edition.

to start transactions with a namespace like /IWFND/MAINT_SERVICE, (the part between the slashes is the namespace) you need to prepend them with a leading /n, e.g. /n/IWFND/MAINT_SERVICE. Or, add them to your user menu.

now, for your problem: in /IWFND/MAINT_SERVICE, find your service and add a system alias (in the lower right part of the screen)

Thank you! I did not know about the namespace.

I have added the following definition:

Service ID: ADT_0001

Alias: LOCAL

Tech: Name: ADT

Ext: ADT_SRV

and now I get a seemingly sane output.
