I have exported all my sale.order (procurements/presupuesots) from openerp and now I wanto import this ones on odoo. Whem I insert the header everything is ok, but when I insert the lines this crash and I get this error:
Misiing error: One of the documents you are trying to access has been deleted, please try again after refreshing
Please I need that urgent
The problem is you missed to provide field mapping to a required field. I assume it to be with "order_id" field. Also check your table structure at SQL level before any import is DONE.
