"Are you sure you have a PK field? Is it unique? What is the field name and what index do you have in your table? Which table did you make updatable?"

Naomi, Excuse my ignorance, what is a PK field? The table I make updatable is the PKG table

I have incorporated your code in the afterrowcolchange of the grid as follows.
No luck yet!

if not tableupdate(.t.,.t.,'VUEpkg')
 local array laError[1]
 =aerror(laError)
 lcError = "Error # " + transform(laError[1]) + " " + laError[2]
 =messagebox(m.lcError)
else && TableUpdate succeed
 flush in pkg
ENDIF
