If you want to shorten this query a little, you can also use aliases as Tables names, e.g.:

select nr3.field1, nr3.field2, etc. ;
  FROM nrh10300 nr3, nrh10200 nr2, nrh14000 nr4;

>>yes, it does run if I remove any other field from the nrh14000 table or any other table. I dont think i've exceed the caracter limit.

SELECT some fields, ... nrh14000.Dir_emp ; <<--- This field is the problem
>	FROM nrh10300 , nrh10200, nrh14000 ;
>	INTO TABLE outrh\Maemp ;
>	WHERE nrh10200.Numemp = nrh10300.Numemp ;
>	AND nrh14000.Numemp = nrh10300.Numemp ;

>You can remove highlighted lines w/o affecting your query because nrh10300.Tnoemp would be less than 'J' or 'P' if it's less than 'B'.
>If query runs than you certainly exceeded a limit.
