RFC Logon Failure : Not Authorized to logon to the target System

[Former Member]

We have developed a program based on Jco Programming using SAP's standard Jco Libraries.

But the time we are trying to call remote enabled function from our program we are getting following error :

(103) RFC_Logon_Failure : You are not authorized to logon to the target system.

Please guide me on the same and please tell what changes i have to made in SAP system which willl resolve the issue which we are facing.

Hi Tanvi,

As mentioned by Ganesh, please check the user's authorization and and also SAPALL temporarily to check.

We have already provided SAP_ALL and SAP_NEW profile to the user.

Please confirm if we need to create some Trusted environment or we need to create RFC destination using SM59

Hi Tanvi,

sm59 is for outogoing connections, you don't need anything there when calling from JAVA to ABAP.  What are the server side traces are saying?

Best regards,

Hi Tanvi,

It's up to you to create the system (RFC Destination) but it should work directly.

Please check the following

1. Are you able to login in SAP System with the same credentials which your passing JCO call. If yes then go to point 2

2. Please put trace on in SAP System for this user so you will come to know that which of the authorization object is missing (take help of a basis guy for this).

Thanks,

Hamendra
