Insert dblink table using views

Question

Hi all,
I' using the next insert query to a dblink table:
INSERT INTO dgy_doc_data@dgtry_dblk (user_id,
                                     doc_xml_data,
                                     created_by,
                                     creation_datetime)
    SELECT   a.user_id,
             a.doc_xml_data,
             a.created_by,
             a.creation_datetime
      FROM   dgtry_view aDGTRY_VIEW it's a view like this:
CREATE OR REPLACE VIEW dgtry_view
    id,
    user_id,
    doc_xml_data,
    created_by,
    creation_datetime,
    esc_sigla
AS
    (SELECT   id,
              user_id,
              doc_xml_data,
              created_by,
              creation_datetime,
              esc_sigla
       FROM   (SELECT   id,
                        user_id,
                        doc_xml_data,
                        created_by,
                        creation_datetime,
                        'FLUP' AS esc_sigla
                 FROM   dgtry_table_flup
                WHERE   (in_d IS NULL OR in_d = 'N')))
    UNION ALL
    (SELECT   id,
              user_id,
              doc_xml_data,
              created_by,
              creation_datetime,
              esc_sigla
       FROM   (SELECT   id,
                        user_id,
                        doc_xml_data,
                        created_by,
                        creation_datetime,
                        'FEP' AS esc_sigla
                 FROM   dgtry_table_fep
                WHERE   (in_d IS NULL OR in_d = 'N')))If I remove the second SELECT statement in the view, I don't receive any errors and the insert is done. But with the second e SELECT and the UNION ALL statement I get the error:
ORA-22992: cannot use LOB locators selected from remote tables
ORA-02063: a preceder line de DGTRY_DBLK
NOTE: the doc_xml_data value it's a BLOB.
I tried everything to turnaround this problem, but I don't have any new ideas. Can you help me?
Thanks in advance.

Just to confirm: Have you tried
insert into dgy_doc_data@dgtry_dblk (user_id,
                                     doc_xml_data,
                                     created_by,
                                     creation_datetime)
select user_id, doc_xml_data, created_by, creation_datetime
  from dgtry_table_flup
where (in_d is null or in_d = 'N')
union all
select user_id, doc_xml_data, created_by, creation_datetime
  from dgtry_table_fep
where (in_d is null or in_d = 'N')?
