I have a canceled intercompany sales order with no lines, and its corresponding intercompany purchase order in another entity remains open. I want to cancel the purchase order, but it also has no lines, and the 'Cancel' and 'Delete' buttons are disabled. The purchase order status is 'Open.' I attempted to edit it through the table browser, but the 'purchaseorderstatus' field is not editable. If I delete the record directly from the table browser, what impact would it have on the intercompany sales order?
