Adding CUA Child - 'Cannot access system using RFC' error

Hi,

We have added a new ERP system to our landscape.

When trying to add a client in new ERP system to our existing CUA setup, we receive error "Message 01395 - Cannot access system &1 using RFC".

I have already checked all the steps like, creating logical systems in BD54 and assignment to clients in SCC4, creating RFCs and checking in both the systems, everything looks fine except that the error persists.

This is not the first time i am adding a child system to CUA, however, this is kind of weird that i have this error. Or may be i am missing a critical step somewhere, or am overlooking something important.

Just to make sure i checked help.sap to see all the necessary steps are followed, including the naming conventions for RFCs and Logical System names etc, with no luck!

Any help/advice to resolve this error would be much appreciated.

Thanks in advance!

Regards,

Naga

    Hi all,

    The issue was with the assigned roles!

    SAP_BC_USR_CUA_CLIENT

    SAP_BC_USR_CUA_SETUP_CLIENT

    The above roles were added to the user maintained in the RFC destination on the Central system to child. However, as the child system was a newly built system, the roles weren't generated with appropriate Profiles.

    Generating the Profiles to above roles and User Master Comparison did the trick.

    Nagaraju,

    Check whether new client is added properly in the CUA configuration in BD64 and generate and distribute the model view.
