2-way, 3-way, and 4-way Matching
When you match to a purchase order, Payables automatically checks that the total of PO_DISTRIBUTIONS.QUANTITY_ORDERED = AP_INVOICE_DISTRIBUTIONS.QUANTITY_INVOICED (2-way matching).
Payables only checks QUANTITY_RECEIVED (3-way matching) if the RECEIPT_REQUIRED_FLAG is set to Y and only checks QUANTITY_ACCEPTED (4-way matching) if the INSPECTION_REQUIRED_FLAG is set to Y.
