Automatic numbering feature in Sales Invoice

The automatic numbering feature in the sales invoice is not working though the option is displayed. Can you please help. Venkat

It is not an option. It happens by itself. If you dont’ want the automatically assigned number, you can edit it after the invoice is created.

The number is not assigned while you are looking at the entry screen. It is assigned when you click Create. This is because is multi-user situations, more than one person might be working on invoices, possibly deleting them to start over, etc., so you could end up with duplicates. Since the automatic numbers are assigned only when the invoice is created, duplicates are avoided.

@Tut, yes this all ok but i agree for sales invoice but this nice feature is not working on sales order, Dietmar
