Acknowledgments
You configure HL7 acknowledgments at the party level using Microsoft BizTalk Accelerator for HL7 (BTAHL7) Configuration Explorer. Acknowledgments apply to parties that are sending HL7 messages through a receive location (possibly the MLLP adapter) and the HL7 2.X receive pipeline. When a message completes parsing and validation, BTAHL7 can create an acknowledgment message that contains the result (success or error) of the validation process. BTAHL7 can return acknowledgment messages in one of two ways. If the original sending party submitted the original message through a two-way receive port configuration, BTAHL7 returns the acknowledgment message through that original port location. If the original sending port submitted the original message through a one-way receive port, then BTAHL7 submits the acknowledgment message into the MessageBox database and routes it using the subscription model.BTAHL7 performs party association for receive message processing automatically based on the value within the sending application field of the HL7 message (MSH 3.1).
