Unable to trace which invoice match to this PO and Receipt

Hi,

Request your guide line to find the invoices which are match to PO and Receipt.

We have a PO 38176 which was raised to purchase multiple items.

Item A0001 was received through Receipt No 10956.

While matching the PO and Receipt through invoice work bench system is not showing the quantity.

if we enter qty one, system shows overbilled message.

It means this PO and receipt was already billed.

We run the matching detail report but report does not gave any invoice detail.

We search the invoice through invoice workbench based on PO number. All the invoices which were created earliers are cancelled.
