Hi villas
thanks for your suggestion.
I ran a test in the shell and it works:
web2py Web Framework

>>> db.tables

'auth_event', 'auth_cas', 'docscan', 'itmscan']
>>> ti=db.itmscan
>>> ss=db(ti.DocNum==350).select()
>>> print(ss)
itmscan.id,itmscan.DocNum,itmscan.ItemCode,itmscan.Dscription,itmscan.box,itmsca

>>> scnqtysum = ti.scanqty.sum()
>>> ss=db(ti.DocNum==350).select(scnqtysum)
>>> print(ss)
"SUM(""itmscan"".""scanqty"")"
2.000000
so something is amiss somewhere...
BTW, having DocNum=='350' makes no difference.
