You have the following options:
1. You can change the user specified in the RFC destination and enter a
dialog user.
2. In the target system of the RFC, you can change the user type of the
user used by the RFC destination to "Dialog".
3. You can also avoid this error by not debugging the RFC.
If the statement cursor in the ABAP Debugger is on the corresponding
statement (CALL FUNCTION ... DESTINATION), the "Execute" function
should be chosen.
RFC debugging only possible with dialog user

To debug ABAP programs, screens have to be displayed; and dialog with
the user is required. It is therefore not possible to perform RFC
debugging with destinations containing users whose user type only
permits dialog-free communication.
An attempt was made to perform RFC debugging with a destination where a
user is entered with a user type that can only be used for dialog-free
communication. This means that it is not possible to debug with a
system user.
