Hello,

It's good practice to use an alias for tablename
when you use several tables or same table many times, so you could add
on your query :

FROM EINKAUFHISTORIE E

select min(e1.effekpreis) as MINI,max(e1.effekpreis) as MAXI,
min(e1.ref0) as
ref0temp from einkaufhistorie e1
where e1.ref0=:MLNK_REF0_0 and e1.effekpreis>0
and F_ADDDAY(e1.datum,<<MINMAXTAGE>>)>='now'

on mm.ref0temp=e.ref0

I dont know how IBOjects handle this without table alias but I suspect
that it couldnt guess the editable status of EINKAUFHISTORIE.

Regards

Alexandre

PS : I think also Fb 20 is less tolerant on that (see Release notes)
