    Hi

    Are you trying to connect to an ABAP system ?

    I would suggest checking the destination system settings that you have configured in the SLD.

    In content administrator ---> start assigned SLD ---> Technical settings

    Also check the default.trc for clues.

    Well, ensure you are using user credentials (correctly entered) have enough authorizations.

    You may stop/start these jco connections from VA/NWA.

    • Hi,

      I will suggest create a system user and assign full authorization to this user and then assign it to JCO RFC then try.

      Also, When you will go in VA and JCO RFC then select that RFC and on bottom you will get stop/start button as a result you can stop individual JCO RFC.

      Thanks
