In an app I have orders are entered into sunsaletbl - through a form.
When the invoice section is entered all records in the sunsaletbl are
grabbed and put into invtranstbl and marked in sunsaletbl.
This all works fine.
However if for example on delivery the customer only takes 5 bottles instead
of 10 ordered, i advise users to enter a new record of -5.
However some insist on making a change in sunsaletbl and because the record
has already been sent to inv that change does not go to invoice
I think the way to fix this is to prevent changes to the record if the
gonetoinv is yes.
Appreciate advice on how to do this
TIA
