USER: Validate Totals

EDTTRN provides you with an extra user point before the DBF update user points. This user point allows you to perform useful validations, in particular, relational checks between a DBF field and a function field. For example, a comparison between a customer’s credit limit and his outstanding balance plus an order total in an Order Entry function. You can then set the program context defer confirm field to do not confirm (PGM.*Defer confirm = *Do not confirm) if the validation fails and you do not want DBF updates to occur.
