When necessary, subscribers of SheduleInterpreter® can now display a letter next to the invoice number, indicating the version or edition of the invoice. The version indicator uses letters, starting from letter A and has no specific end requirements. Each time an invoice undergoes a correction of any type, the platform will automatically increase the version indicator. Indicator can be used together with REVISED tag. To include the version control indicator, use DOCUMENT DESIGNER and add {invoiceVersion} keyword anywhere in the layout of the invoice header.
