Instance IDs for Functional Acknowledgments
It is recommended that you use the following instance IDs for functional acknowledgments (FAs):
* For an ANSI X12 997, use ST/AK1/AK102, which corresponds to the group control number.
* For a UN/EDIFACT CONTRL message, use UCI/03, which corresponds to the interchange control number.
