Iam from SAP Authorizations team. Iam having one query. One user is not able to login in central instance, it is showing an error message as you are not authorized. But the same user is able to logon from Application server.
How to solve this issue? kindly explain.
First Let me know whether you are using CUA concept or not...
If yes the call the transaction code SCUL (on CUA system) and enter the user name and execute it. It will show the information related to the user that the particular user available in the central instance or not.
Kindly revert if the issue not solved.
