to check the possibility double invoice, there is a check box when you create a vendor account group that should be checked.
After you check this box, it will check if that invoice already exists.
However, if you are trying to verify the invoice against the goods receipt or the purchase order, use tcodes MIGO and give the goods receipt number or the purchase order number and the system will check the invoice against those documents.
