Deleting Thirdparty order When PO already GR archived
We have a third party sales order which is still in open status.Year 2006 orders.
Corresponding PO already created and GR already completed.
we wanted to set reason for rejection in sales order but system is not allowing untill you delete the PR and PO.
We already set deletion indicator in PO but as a stnd process we first need to cancel GR IR and then set deletion indicator in PO and and then set deletion indicator in PR and then delete the line item in SO.
Problem now is we could not cancel the GR as this is already archived.
So, is there any way to delete the PO and PR and complete the status of SO?
Or Is there any utility program that can change the status of the order to Complete?
