Matching a Purchase Order with a Functional Acknowledgement

Now that we are armed with the knowledge of elements, segements, and envelopes, we have the aptitude to match incoming 850 Purchase Orders with outgoing 997 Functional Acknowledgements. First, the important link that matches the purchase order to the functional acknowledgment is known as the group control number. In the purchase order, the group control number is contained in the element GS06, while it can be located in the functional acknowledgement at the element AK1. The group control number is what allows us to match a purchase order with a 997.
