Is it possible to delete an incoming document on a purchase order, but keep it on related purchase order invoices?
I want to delete finished purchase orders, but when a purchase order is deleted, validation of the Posted field on Incoming Document is triggered, so the purchase order can not be deleted. The only way I can make it work, is by going to "Prepare -> Incoming Document -> Remove Incoming Document" on the PO, but then the Incoming Document is also removed from the Posted Purchase Invoice.
I guess I'm missing something, since it should be possible to delete the purchase order and keep the document on the posted purchase invoice?
