Need help with the proper SQL syntax when querying a linked Server

I am currently using this statement to query a linked Server:

INSERT INTO WOMAST01
SELECT * FROM OPENQUERY(ATQAV, 'SELECT * FROM WOMAST01')

Select allOpen in new window

and it works fine.

I want to add a WHERE clause to filter by date using the RECDATE field. I try

INSERT INTO WOMAST01
SELECT * FROM OPENQUERY(ATQAV, 'SELECT * FROM WOMAST01 WHERE RECDATE > '20140101'')

Select allOpen in new window

but it is not working, error received:  Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '20140101'.

What is the correct syntax?
