To use the automatic invoice rounding function, you must set up the general ledger account or accounts where rounding differences will be posted. Before you can do this, you must set up VAT product posting groups.
To set up general ledger accounts for invoice rounding differences
In the Search box, enter Chart of Accounts, and then choose the related link.
Set up the account in the Chart of Accounts window and name it Invoice Rounding or something similar. Microsoft Dynamics NAV will use the account name as text for invoices that are rounded.
In the Gen. Posting Type field, select <Blank>.
Leave the VAT Bus. Posting Group field blank.
Fill in the VAT Prod. Posting Group field. You may want to set up a new group code that can be used for invoice rounding.
