"You can't save this record at this time"

[an]

I have a Form to insert data in Table.

In process, when we run code:

.. . .
If MsgBox(strField, vbYesNo + vbExclamation, _
"Msg") = vbYes Then

Me(strField).SetFocus
Cancel = True

Else

Me.Undo
End If
End If
End Sub


and after this MsgBox, if we click No, abort without save.
If we click Yes, appear the Access Menu for to continue,
pparently, without making sensible, with message:

"You can't save this record at this time"

Is it possible to omit it, please?

Thanks in advance.
