Thank you very much, for your advice, but something is still wrong, because it doesn't work.
 
I get the following message: parse error at or near "on"
 
I tried the Left Join with an easier query, but it still doesn't work. Maybe you see, what I'm making wrong
select artikel.a_nr,artikel.a_bez1,artikel.a_bez2 from Artikel
LEFT JOIN (vartikellieferantbez ON (artikel.a_nr = vartikellieferantbez.a_nr AND vartikellieferantbez.f_nr=1 ));
 
Many thanks,
Irina

Your "where" clause for an OUTER JOIN is actually the ON statement.  So do this: 

LEFT JOIN (vartikellieferantbez ON (artikel.a_nr = vartikellieferantbez.a_nr  AND
vartikellieferantbez.f_nr = 1))
