Hello!

I'm trying out the OpenErp 7. I have created an initial inventory with products, but the inventory is not finished yet and is not validated. Then I tied out the customer invoice. I have created one, but I want to delete it. I installed the Account_cancel module, checked out the Accounting > Journals > Allow canceling entries box. But I still can't delete the invoice. When I try to delete it I get the following:

You cannot delete an invoice which is not draft or cancelled. You should refund it instead.

Also I have tried a Customer refund too. There I can't delete it either and I get the following warning:

You cannot delete an invoice which is not draft or cancelled. You should refund it instead.

How could I delete the two entries? Also probably until the invoicing will be OK, I will have to try the invoicing so I might delete some of the try out invoices too. Thank you for your help.
