If the record linked to an order line is merged with another record, bibliographic information is lost in order line, because it is linked to a deleted biblionumber. Solution : When Koha merges 2 records, it should check if the record that is going to disapear is used in an order. If it is so, it should update the order line by replacing the old biblionumber by the biblionumber of the resulting record. M. Saby Rennes 2 university
