Context
You want to access resources in an application that is OAuth 2.0 enabled. For this
application, you need a registered OAuth 2.0 client as the accessing component. The OAuth
2.0 client has a dedicated unique user in the AS ABAP of the user type
System. If this user does not exist, create it
in your AS ABAP.
This registered OAuth 2.0 client represents an OAuth 2.0 enabled
application which is then able to access the user's resources on behalf of the
user.
