11.2.0.3, DBMS_DATAPUMP import ower db link, DATA_REMAP does not work

Question

This is related to impdp: should network_link and remap_data work together? that I accidentally marked as answered.
Documentation says, I can supply NULL as value of schema for DATA_REMAP: See   DBMS_DATAPUMP
That does not work, it gives an error:
ERROR at line 1:
ORA-39001: invalid argument value
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 79
ORA-06512: at "SYS.DBMS_DATAPUMP", line 3507
ORA-06512: at "SYS.DBMS_DATAPUMP", line 4309
ORA-06512: at line 11
If I give SOURCE_SCHEMA as schema, DATA_REMAP does nothing.
TARGET_SCHEMA is of course not accepted as TABLE_TO_LOAD does not yet exist.
The code I am using is something like this:
set serveroutput on;
declare
  handlename number;
begin
    handlename := DBMS_DATAPUMP.open('IMPORT','TABLE', 'SOURCE_DB_LINK','NAME_OF_JOB');
    DBMS_DATAPUMP.METADATA_FILTER(handle => handlename, name => 'SCHEMA_LIST', value => '''SOURCE_SCHEMA''');
    DBMS_DATAPUMP.METADATA_FILTER(handle => handlename, name => 'NAME_EXPR', value => 'IN (''TABLE_TO_LOAD'')');
    DBMS_DATAPUMP.METADATA_REMAP(handlename,'REMAP_SCHEMA','SOURCE_SCHEMA','TARGET_SCHEMA');
    DBMS_DATAPUMP.ADD_FILE(handlename, 'name_of_log','DUMPDIR',NULL,DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE,1);
    DBMS_DATAPUMP.DATA_REMAP(handlename, 'COLUMN_NAME', 'TABLE_TO_LOAD', 'COLUMN_TO_REMAP',  'TARGET_SCHEMA.REMAPKG.REMAPFN',  NULL);
    DBMS_DATAPUMP.START_JOB(handlename);
end;
Any ideas?

Hi,
seems it is not supported for Network link check this: Ref Doc:DBMS_DATAPUMP
Usage Notes
The DATA_REMAP procedure is only supported for Export and Import operations. It allows you to manipulate user data being exported or imported. The name of the remap determines the remap operation to be performed.
I haven't try this but, are you using the same user/schema name for the data pump operation where your object exist.. if not you can try this option as well. in that case NULL support i believe.
