You are right, you cannot void the Purchase Order Receival, due to internal complexity.
But you can make an Inventory Adjustment, Negative adjustment, for the items and set the price to 0. This will not create a GL transaction.

Dear Joe,

Thanks for your supports.

If you have already registered the supplier invoice, you just void thie supplier invoice before voiding the Receival (GRN).

Dear Joe,

Sorry for asking again, I can't find the Receival ( GRN) at the voiding menu. I'm using the 2.2.5 version.

Thanks for your supports.

If you are voiding a PO, it is not recorded in the Journal Entries yet. Look at it in the Purchasing Orders in Supplers tab.

Dear Joe,

Thanks for your fast reply. My problem now is the item already received. Some of the invoice, I had VOID but the item quantities are remain there. How to void the received item ?

Thanks for your supports.

You can reverse this transaction by voiding it. Select the transaction type and number. You get an option to look at the transaction before voiding it.

Sorry for asking... what's the transaction to void ? I try to look by journal inquries for PO order deliveries but none ? How to void Outstanding GRN's ?

Thanks for your supports.
