Calling Remote function tool leads always to a logon screen

Hello,

I run an remote function tool in system A. In System B I run a report calling this function module.

Each time, I execute the report, a remote logon screen appears. It looks the same like the one you logon the system. You have to specifiy client, user and password.

I know one possibilty to avoid this logon screen appeaering.

System B (holding the function module) must declare System A as a trusted system. Thus, the user does not need to logon system B, each time calling the func. module. I processed this in correspondence with the help data, but the screen still appears.

Is there any other possibilty to avoid appearing the logon screen or does anybody know wheter I did something wring??

thanks, holger

    Hi Holger,

    Check in the interface parameters of the RFC, if fields for the login details can also be passed along with the data.

    Hi Holger,

    1. This has to do with tcode SM59 (Maintain RFC Connections)

    [

    THE CALLING SYSTEM HAS NOT DEFINED

    USER ID / PASSWORD TO LOGON TO THE TARGET SYSTEM.

    HENCE, IT SHOWS BLANK LOGIN SCREEN

    ]

    2. Under the node RFC Destinations ---> R/3 Connections,

    various systems are defined for RFC Purpose.

    3. Lets say ur system(which u want to connect) is PRD.

    4. Double Click PRD and go the the details.

    5. There are 3 Tabs. Goto LOGON/SECURITY TAB.

    6. In the logon information , enter the

    USERID and password and client.

    7. Save.

    Then try your program.

    Hope this helps.

    Regards,

    Amit Mittal.

    Hi again,

    1. What i understand is this :

    In System B, thru sm59

    System A has been defined as a TRUSTED SYSTEM.

    2. One possibility might be :

    In the same tcode SM59,

    same tab Logon/Security

    There is on checkbox for LOGON SCREEN. (Right to the radio buttons of trusted system N Y )

    If that checkbox is ticked, then also

    such thing can happen.

    If it is checked, just remove the check

    and try once more.

    Hope this helps.

    Regards,

    Amit M

    What we do is:

    Create a user (say RFCUSER) in system A (the called system) and give it only the authorizations needed to run the FM there.

    In system B, in SM59, create a new destination (say DESTA). Enter the userid and password.

    When calling the FM from system B, use the new destination.

    Looking back at the other responses to this thread, I think this is what Ravi is saying.

      I don't know if you have to define system A as trusted in System B. I was just trying to say that in system A, using SM59, you can pass the userid and password when you define the destination for system B. That should keep the password screen from appearing.
