Strange difference in behavior between V6 and V7, on an SQL View opened for native RLA

Got a really weird one here.

Given a rather complex SQL view, with three sub-views UNION ALL'd 
together, which was created on a V6 box, and then restored from a save 
file on a V7 box.

If we use our QuestView utility (native Record Level Access, called from 
OPM MI) to look at this view, on a V6 box, it works just fine, I can 
step through the file at will, and these messages appear in the joblog:

>  Arrival sequence ignored for member FOO.        
>  Open of member FOO changed to SEQONLY(*YES).    
>  Open of member FOO changed to SEQONLY(*YES).    
>  Buffer length longer than record for member FOO.
>  Open of member FOO changed to SEQONLY(*YES).    

All well and good. But on the V7 box (and remember, this view was 
created under V6, and retrieved from a save file), QuestView craps out, 
and I get this in the joblog:

> Arrival sequence ignored for member FOO.                          
> Operation for program device or member FOO, file FOO in     
>   library FROBOZZ is  not valid.                                       
> I/O is not allowed because the program device or member FOO file  
>   FOO in library FROBOZZ is in error.                            
> Error message received by QuestView. See messages in job log for details

I immediately noticed the "SEQONLY" message is absent (I tried an OVRDBF 
with SDQONLY(*YES), and there was no change in the result).

The "Operation . . . is not valid" message is a CPF5149, sent from 
QDBSIGEX to QuestView's master MI program, at an instruction that calls 
the RLA runtime to do the equivalent of an RPG SETLL (by RRN).

The "I/O is not allowed . . . " message is a CPF5129, sent from QDMIFERR 
to the master MI program, at an instruction that calls the RLA runtime 
to do the equivalent of an RPG READ (again, by RRN).

Can anybody here shed any light on this?
