There are several reasons that the total amount due doesn't display properly on an invoice document (or AR Invoice Header). These could include:
- The statement date system parameter does not match the date for the AR invoice item
- Remember — the public value for the date of the statement date system parameter should match the AR invoice item date, not only the user value. The public value and user value for the can be quickly accessed and updated by running the "Update System Parameters" procedure in the action menu and clicking the "Link to System Parameter record" link to the right of "AR Statement Date".
