Step 6: Create a Send Port to Deliver Acknowledgments

In this step, you create a port to send acknowledgments back to the source of the batch.

You create this port to be static, so that it will only be associated with an MLLP adapter, and it will only send to a specific destination (the source of the batch). In this tutorial, the source is associated with the party Tutorial_BatchSource. This source party is contained in MSH3 of the individual messages and FHS3 and BHS3 of the original batch.

You create the port with filters that restrict the port to sending acknowledgments, not data messages. These filters specify a message type of ACK_024_GLO_DEF and a destination of Tutorial_BatchSource.

You configure this send port to receive acknowledgments from the destination, by associating the send port with a receive port named TwoWayAckReceivePort. BTAHL7 setup creates this port, and the accompanying receive location of TwoWayAckReceiveLocation. You set the send port up to work with this port by setting Solicit Response Enable to No and setting the Submit Receive Location URI to 127.0.0.1:65535 (the settings required to accept ACKs). For more information, see Setting Up a Send Port for Receiving ACKs.

To create a send port to deliver acknowledgments

1. In the BizTalk Server Administration Console, right-click Send Ports, point to New, and then click Static One-way Send Port.

2. In the Send Port Properties dialog box, do the following:

   Use this	To do this
   Name	Type Tutorial_2wayAck.
   Transport type	Select MLLP from the drop-down list.
   Configure	Click Configure to open the MLLP Transport Properties dialog box.

3. In the MLLP Transport Properties dialog box, do the following:

   Use this	To do this
   Connection Name	Type 2wayAck.
   Host	Type localhost.
   Port	Type 41002.
   Solicit Response Enabled	Keep the field as No.
   Submit Receive Location (URI) for ACK	Type 127.0.0.1:65535

4. Click OK.

5. In the Send Port Properties dialog box, for Send pipeline, select BTAHL72XPipelines.BTAHL72XSendPipeline.

6. In the console tree, click Filters, and then do the following:

   Note

   Ensure that you enter the following data exactly as shown. This data is case-sensitive.

   Use this	To do this
   Property (first line)	Click the field under Property, then select BTS.MessageType from the drop-down list.
   Operator	Select == from the drop-down list.
   Value	Type http://microsoft.com/HealthCare/HL7/2X#ACK_24_GLO_DEF.
   Group By	Select OR from the drop-down list.
   Property (second line)	Click the field under Property, and then select BTS.MessageType from the drop-down list.
   Operator	Select == from the drop-down list.
   Value	Type http://microsoft.com/HealthCare/HL7/2X#ACK_25_GLO_DEF
   Group By	Select And from the drop-down list.
   Property (third line)	Click the field on the second line under Property, then select BTAHL7Schemas.MSH5_1.
   Operator	Select == from the drop-down list.
   Value	Type Tutorial_BatchSource.

   Note

   The first filter means that you are subscribing to the acknowledgment message. The second filter means that you want the acknowledgment that has the destination of the publisher, Tutorial_BatchSource.

7. Click Enter. In the pane at the bottom of the dialog box, verify that you entered the filter expression correctly, and then click OK.

8. In the Administration Console, click Send Ports, right-click Tutorial_2wayAck, and then select Start.

   Note

   For the Tutorial_2wayAck send port to function properly, you must enable the TwoWayAckReceivePort receive location.

9. Click Receive Locations. Verify that the status for the TwoWayAckReceiveLocation is enabled. If not, right-click TwoWayAckReceiveLocation, and then click Enable.

   Proceed to Step 7: Create and Configure a Source Party.
