Close a PO without any impact on Accounting Entries/Bills/Invoice.

Hello,

Is it possible to close a Purchase Order without any impact on Accounting Entries or Invoice/Bills ?

I have the following cases which requires to close certain Purchase Orders without any impacts.

1 - Some POs have been paid by checks and or disbursements.

2 - Some POs' articles have been paid and others not, and some have been delivered while some were not delivered.

3 - The payment attached to the PO is not reflecting the amount of the PO.

In these cases, please advise if a PO Return applicable and manually close the PO is suitable? Or are there any other ways which can be used to close the PO without generating any issues on the Accounting Level?
