Matching a Functional Acknowledgement with an Invoice

Matching a Functional Acknowledgement with an Invoice

This lengthy chart demonstrates the flow of an 810 Invoice sent from your server to a trading partner's, as well as the subsequent reply of a 997 Functional Acknowledgement from the trading partner to you. The key to the smooth flow of this diagram is the control number, found in the element "GS06" of the invoice. The trading partner sends that specific control number in the "AK1" segment of the 997 Functional Acknowledgement in order to signify which invoice the 997 is being sent for. It is this control number that allows us to match a given Functional Acknowledgement with its corresponding Invoice.
