Invoice Numbering Problem (Delivery Slip Before Invoice)

[bcarron]

Hi,

 

I've got a problem since a while where a lot of my orders were accumulating on the day I started using prestashop (back in march). On the stats screen I have a big spike on the day of the first order and all the money start counted on that day. I first thought that it was a problem on the stats dashboard but since it's been a long while now, I started investigate. 

 

The problem seems to be that a lot of my orders have the same invoice number: #IN000000. I have made a new order status to be able to get the delivery slip before actual payment from the customer so that I can prepare the parcel with the slip. It seems that every order with this status in its history got the wrong invoice number 0...

 

Is there something I can do to correct the stats and the invoices?

 

Thanks in advance

I tried to put the delivery slip directly in the "awaiting bank wire payment" but it doesn't work either. It messes up both the invoice and the delivery slips... This is stupid!

Ok, I have corrected the invoice numbers manually in the database. Now the invoices are generated correctly but the stats are still wrong in the dashboard. Does anyone knows how these stats are gathered and how I can modify them?
