Hello
If you linked the document class with an outgoing port, first unlink the class from the port.
Then, after having created or updated the document services, please go to the apropriate service in AOT, right click and choose "Add-Ins" / "register service". In the new window, you can refresh the services.
Now you should be able to link the document class with new schema to the outgoing port.
Then please perform a ful CIL and restart the AOS.
If you run the service with a batch job, you have to delete the old batch job before and recreate a new one, because the execution class is cached in the batch job.
Tell us, if this helps
Regards
Hans-Peter
