AP Invoice for Inventory item

SOLVED

Once of our employees adjusted the inventory of an item instead of receiving it through Receipt of Goods entry.  I now have an invoice for that PO, but don't know if I should just do receipt of invoice?  or enter through AP.  If I use receipt of invoice, I think that the PO will remain open since it will think that the product was never received.  If I use AP Invoice data entry, I don't know which GL account to use.

Anyone run into this issue?
