DATA PUMP API returning ORA-31655

Question

Hello Gurus,
I am using below code to import a table(EMP) from one Database to Another using Network.
set serveroutput on;
DECLARE
ind NUMBER; -- Loop index
spos NUMBER; -- String starting position
slen NUMBER; -- String length for output
h1 NUMBER; -- Data Pump job handle
percent_done NUMBER; -- Percentage of job complete
job_state VARCHAR2(30); -- To keep track of job state
le ku$_LogEntry; -- For WIP and error messages
js ku$_JobStatus; -- The job status from get_status
jd ku$_JobDesc; -- The job description from get_status
sts ku$_Status; -- The status object returned by get_status
BEGIN
h1 := DBMS_DATAPUMP.OPEN('IMPORT','TABLE','DBLINK',NULL,'LATEST');
DBMS_DATAPUMP.METADATA_FILTER(h1,'NAME_EXPR','IN (''SCOTT.EMP'')','TABLE');
DBMS_DATAPUMP.SET_PARAMETER(h1,'TABLE_EXISTS_ACTION','REPLACE');
DBMS_DATAPUMP.METADATA_REMAP(h1,'REMAP_SCHEMA','SCOTT','SCOTT');
--DBMS_DATAPUMP.METADATA_FILTER(h1,'INCLUDE_PATH_LIST','like''TABLE''');
DBMS_DATAPUMP.METADATA_REMAP(h1,'REMAP_TABLESPACE','USERS','USERS');
DBMS_DATAPUMP.SET_PARALLEL(h1,8);
begin
dbms_datapump.start_job(h1);
dbms_output.put_line('Data Pump job started successfully');
exception
when others then
if sqlcode = dbms_datapump.success_with_info_num
then
dbms_output.put_line('Data Pump job started with info available:');
dbms_datapump.get_status(h1,
dbms_datapump.ku$_status_job_error,0,
job_state,sts);
if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0)
then
le := sts.error;
if le is not null
then
ind := le.FIRST;
while ind is not null loop
dbms_output.put_line(le(ind).LogText);
ind := le.NEXT(ind);
end loop;
end if;
end if;
else
raise;
end if;
end;
-- The export job should now be running. In the following loop, we will monitor
-- the job until it completes. In the meantime, progress information is
-- displayed.
percent_done := 0;
job_state := 'UNDEFINED';
while (job_state != 'COMPLETED') and (job_state != 'STOPPED') loop
dbms_datapump.get_status(h1,
dbms_datapump.ku$_status_job_error +
dbms_datapump.ku$_status_job_status +
dbms_datapump.ku$_status_wip,-1,job_state,sts);
js := sts.job_status;
-- If the percentage done changed, display the new value.
if js.percent_done != percent_done
then
dbms_output.put_line('*** Job percent done = ' ||
to_char(js.percent_done));
percent_done := js.percent_done;
end if;
-- Display any work-in-progress (WIP) or error messages that were received for
-- the job.
if (bitand(sts.mask,dbms_datapump.ku$_status_wip) != 0)
then
le := sts.wip;
else
if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0)
then
le := sts.error;
else
le := null;
end if;
end if;
if le is not null
then
ind := le.FIRST;
while ind is not null loop
dbms_output.put_line(le(ind).LogText);
ind := le.NEXT(ind);
end loop;
end if;
end loop;
-- Indicate that the job finished and detach from it.
dbms_output.put_line('Job has completed');
dbms_output.put_line('Final job state = ' || job_state);
dbms_datapump.detach(h1);
-- Any exceptions that propagated to this point will be captured. The
-- details will be retrieved from get_status and displayed.
exception
when others then
dbms_output.put_line('Exception in Data Pump job');
dbms_datapump.get_status(h1,dbms_datapump.ku$_status_job_error,0,
job_state,sts);
if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0)
then
le := sts.error;
if le is not null
then
ind := le.FIRST;
while ind is not null loop
spos := 1;
slen := length(le(ind).LogText);
if slen > 255
then
slen := 255;
end if;
while slen > 0 loop
dbms_output.put_line(substr(le(ind).LogText,spos,slen));
spos := spos + 255;
slen := length(le(ind).LogText) + 1 - spos;
end loop;
ind := le.NEXT(ind);
end loop;
end if;
end if;
END;
when i run the same code and change the mode for SCHEMA LEVEL import it is working fine.
But when i want to import a single table it is giving below error
Data Pump job started successfully
Starting "SCOTT"."SYS_IMPORT_TABLE_06":
Estimate in progress using BLOCKS method...
Processing object type TABLE_EXPORT/TABLE/TABLE_DATA
Total estimation using BLOCKS method: 0 KB
ORA-31655: no data or metadata objects selected for job
*** Job percent done = 100
Job "SCOTT"."SYS_IMPORT_TABLE_06" completed with 1 error(s) at 20:56:23
Job has completed
Final job state = COMPLETED
can you give any suggestions on this error.
Thanks in advance
