In Italy, as per legal requirement the invoices and credit memos must be reported in a sequential numbering format.
The official document number (ODN) assigned to such documents must be consecutive without gaps. Earlier, the document number was generated on save of invoices but the posting was allowed only if the previous documents were posted..
To make the posting simpler a new sequential document number field is introduced . Now the official document number is generated on posting of invoices based on the numbering configuration in the business configuration work center and is displayed in the new sequential document number field.
With this new change, the number generated on save of invoices is a global number which will be used only for reference purposes and won’t be considered official number hence forth.
The incoming VAT returns for Italy will also reflect the ODN number as per the new sequential document number.
