ORA-39001: invalid argument value

ORA-39202: Data cannot be filtered or selected in ESTIMATE_ONLY jobs.

According to oracle support this is reported as BUG in 11gr2, we cannot filter the data rows when doing ESTIMATES at the same time

“Bug 9536364 : DOC: DATA_FILTER AND ESTIMATE OPTIONS CANNOT BE USED TOGETHER IN DBMS_DATAPUMP”

Action: Do not restrict data handling on jobs that cannot support data filtering.
