Service not prompting for UserID/password for SAP Gateway

0 Kudos

Hi,

We are facing a strange issue.

We have MXX-200 system which is configured as a gateway system for SXX-200(Dev system), and MXX-300 is configured as a gateway for SXY-300(Testing System). We have checked every configuration and compared them between these two systems, and made every config uniform. Still, while accessing the service from MXX_200, it is prompting for a userID/password, but no such password is been asked for MXX-300. Further, which doing test-service, we are facing the error as "RFC Error: User misses authorization object S_RFCACL in target system".

The RFC used as a gateway is configured a 'Current User' type, still no prompt for UserID/password.

Any ideas on this would be very helpful. This issue is pending since a month. I have re-created all the trusted RFCs, and made all changes as compared to the dev system, still no luck.

Please help.

Regards,

Soumyojit

Hi Soumyojit,

Before speaking about the error message you are getting let's check that you configured connections correctly.

MXX and SXX will connect using trusted connections. You need to configure your backend system to be the trusting system and the frontend as the trusted system. You do this by creating the destination in the frontend with the logon to use the current user, as you did, and checking the Truted Relationship flag.

Then, in your backend system, after creating the RFC destination you will setup the trusted relationship using transaction SMT1. You follow the wizard and that will set everything up.

If you are getting the error message

"RFC Error: User misses authorization object S_RFCACL in target system".

Is easy to check. Right after receiving that message log on to the backend with the same user and execute transaction SU53. That should display the authorization check that failed.

Every user that will work with this type of connection needs to have object S_RFCACL in both systems. I advice you to have a look at this 2 links:

I hope this helps.

Hi Soumyojit,

On the RFC error can you check with Authorization team to provide access to S_RFC object in both system.


we are facing the error as "RFC Error: User misses authorization object S_RFCACL in target system".

Check some of these doc.

Authorizations - RFC/ICF Security Guide - SAP Library

Authorization Object S_RFCACL - RFC/ICF Security Guide - SAP Library

On the other issue of prompting of user ID/Password can you check once if RFC is having trust relationship.
