V5R3 and logical files

We just upgraded to V5R3 and we are having trouble with a couple of 
queries that are using a logical file (which is a separate topic) that has 
RENAMEd fields in it.  If we remove the RENAMEs from the *LF, the query 
works OK.  These queries have always worked well; this is the first time 
they fail.

Message . . . . :   Field ITNBR not found in file *N in *N.  
Cause . . . . . :   Field ITNBR from query format @HISTIF could not be 
found 
  in file *N in library *N format *N join reference 0.  If the file name 
is 
  *N, the field was not found in either the query record format or the 
queried 
  file formats. If the file name is *FUNCTION, the file was user-defined 
table 
  function *N in library *N.  


Physically, the field is ITNBR but in the logical is RENAMEd to AAA123. 

Any reasons why I have this with V5R3?

TIA,
