The selected billing order cannot be deleted because it was generatedby the adjustment reversal of billing document &v1&.
In most cases the billing order is rebilled: the line items of thebilling document &v1& that was reversed for adjustment are included inthe new billing document as negative values. This produces a differencebill based on the fact that the corresponding invoicing document wasnot reversed during the adjustment reversal of document &v1&.
