Recently, my orders in 'Orders Maintenance' list in admin are incremented one higher than the packing slips and invoices for the same order.
In other words, Order 7531 is shown as 7530 on the Invoice and the Packing slip.
Best way to resolve that??
UPDATE: seems no matter what order, as far back as I can tell, any new invoice or packing slip is -1 from the order number. Sounds like a database+script issue, perhaps from a failed row in the db.
I didn't realize that. IT is mass confusion when invoices and orders do not match, however. A more understandable situation would be for orders and invoice numbers to always match, and apply a serial number for other purposes.
