The X12 tab of the Trade Agreements screen for outbound maps lets you specify whether a TA1 interchange acknowledgement should be requested for communications with the trade partner.
To require a TA1 interchange acknowledge, select the Request TA1 Interchange Acknowledgement check box on the X12 tab of the Trade Agreement screen. A check in this box indicates that there is an agreement between the sender and receiver that the receiver will send an interchange acknowledgement confirming the receipt of the ISA envelope.
