The sql part of the view is:

SELECT Plugtrays.id, Plugtrays.pretype, Plugtrays.week,;
  Plugtrays.positions*Plugtrays.nosown*Plugtrays.prcnt/100 AS seedlings;
 FROM ;
     production!plugtrays;
 WHERE  Plugtrays.detl_idno = ( ?v_plandetls.detl_idno );
 ORDER BY Plugtrays.id

Plugtrays.id = C5
Plugtrays.pretype = C15
Plugtrays.week = C2
Plugtrays.positions = N4
Plugtrays.nosown = N5
Plugtrays.prcnt = N3

v_plandetls.detl_idno is provided by the app at run time ; both v_plandetls.detl_idno and Plugtrays.detl_idno are C6.

I have rebuilt the view with a completely different name in the dbc and still get the error in the app but not when browsing the view directly.

I am beginning to think that the Error message is spurious and in fact there is something else going on....
