Can anyone please help with this!!

I have used the Oracle upsizing wizard to get my database onto Orcale.
Everything has gone over including the relationships, indexes, etc.

My problem is when i try to add a record for e.g.

select company
mcomp = thisform.txtcompany.value
replace name with mcomp
=tableupdate(.T.,.T.)
=SQLCOMMIT(gnConnHandle)

It comes back with the message "UPDATE FAILED"

Does anyone have a solution to this?
Many Thanks in advance :)
