RFC DEstination Error

Question

After creating the Destination in sm59 I tested the connection.
When testing the connection, it gives the result as
Connection type:    R/3 connection

Here's a full text of the error I receive
<b>Error when processing your request
What has happened?
The URL http://<host_server>.com:<port>/sap/bw/BEx was not called due to an error.
Note
The following error text was processed in the system BQ1 : com.sap.engine.services.rfcengine.RFCException: Incoming call is not authorized
The error occurred on the application server <host_server> and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Form: IF_RSRD_F_DISTRIBUTOR_RT~DISTRIBUTE of program CL_RSRD_DISTRIBUTOR_KM========CP
Form: EXECUTE_NODES of program CL_RSRD_SETTING===============CP

Form: EXECUTE_NODES of program CL_RSRD_SETTING===============CP
Form: EXECUTE of program CL_RSRD_SETTING===============CP
START-OF-SELECTION of program RSRD_BROADCAST_PROCESSOR
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system BQ1 in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server <host_server> in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server <host_server>. In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
