I have achieved USS registration on my co-deployed system using this thread :
I am successful in creating and activating the user, however when I am trying to see the newly created user in SU01 or trying to login into system using new user, it is stil not allowing me to login. (User does not exist). I am able to look into user profile using OData service /IWBEP/USERMANAGEMENT/UserCollection('newuser'). I have created a user of type service and assigned him SAP_ALL group. Is there anything that I am missing?
