SQL & PL/SQL :: No Entries In Materialized View Log For Insert Append?

I've created a materialized view log on table with the following statement:

CREATE MATERIALIZED VIEW LOG ON table_a
WITH ROWID, SEQUENCE (column_a, column_b, column_c)
INCLUDING NEW VALUES;

The insert is done with the following statement:

INSERT
/*+ APPEND PARALLEL("table_a") */
INTO
"table_a"
("column_a",
"column_b",
"column_c",
"column_d_sum")
(select
column_a",
"column_b",
"column_c",
"column_d_sum"
from table_B)

But the Log is empty when the insert is finished. When I insert rows without the APPEND hint, rows are created in the log table. So, doesn't the log record bulk loads?
