A new welcome addition has been linked to Sales and Purchase documents within Dynamics NAV 2015 that displays the cumulative Total of the document and associated Discount. This applies to Quotations, Orders, Blanket Orders, Invoices, Credit Memos and Return Orders for both Receivables and Payables.
It is now possible to see at a glance the Totals for any such document and replaces the need to come out of the active page and refer back to the Statistics screen. When posting a Purchase Invoice it will be easy to see immediately any discrepancy in the VAT Amount.
The fields are placed on the document page below the Lines section.
The functionality also extends to the equivalent Posted documents as seen here in an example of a Posted Purchase Invoice.
You can also change the Invoice Discount Amount in the Total fields and this will adjust the Total. It will display the calculated Invoice Discount %. Similarly, this will be carried through to any posted document.
