Is there some error log for wb_rt_api_exec.run_task?

Question

Hi,
I am trying to execute a mapping using "wb_rt_api_exec.run_task" by executing the following
declare
result_num number;
begin
result_num:= NEW_OWNER.wb_rt_api_exec.run_task('NEW_USER', 'PLSQLMAP', 'TEST_MAP', ',', ',', 0 ,0);
end;
And this is the output that I get:
Stage 1: Decoding Parameters
| location_name=NEW_USER
| task_type=PLSQLMAP
| task_name=TEST_MAP
Stage 2: Opening Task
| l_audit_execution_id=167
Stage 3: Overriding Parameters
Stage 4: Executing Task
| l_audit_result=3 (FAILURE)
Stage 5: Closing Task
Stage 6: Processing Result
| exit=3
Command was executed successfully
Now I have no idea why the execution of task failed? Is there some log file where I can lookup what the error is?
Thanks,

I had seen the error in Execution log accessed through Repository browser.
But Ive resovled it now.
Actually, the user (NEW_USER) connected to with sqlplus did not have privileges on the registered location - so I connected to OWB Design Center as that user(NEW_USER) and registered the location entering the password. Thats it. It worked!!
