8. In the BizTalk Expression Editor, type or copy the following:

   Message_Task = Message_PO;  
   Message_Task(WSS.ConfigOverwrite) = "no";  
   Message_Task(WSS.ConfigNamespaceAliases)= "orchns='http://OrderProcess.PurchaseOrder'";  
   Message_Task(WSS.ConfigPropertiesXml) = "<ConfigPropertiesXml><PropertyName1>Title</PropertyName1><PropertySource1>Approve %XPATH=//orchns:PurchaseOrder/orchns:PurchaseOrderID%</PropertySource1><PropertyName3>Status</PropertyName3><PropertySource3>Not Started</PropertySource3><PropertyName4>Priority</PropertyName4><PropertySource4>(1) High</PropertySource4></ConfigPropertiesXml>";  
   

   Important

   These values supplied for these context properties are case sensitive. When setting configuration values for a dynamic port with context properties you must ensure that you use the proper case or an error will occur when BizTalk attempts to route the document to the designated send port.

9. Click OK.

10. Click File, and then click Save All.

Build the BizTalk project

Start a new send port

1. Click the Send Ports node.

2. Right-click OrderProcess_1.0.0.0_OrderProcess.MyCompanyOrderProcess_SendToTasksList_<GUID>, and then click Start.

Bind the orchestration

In this procedure you bind the orchestration to the specified ports. This procedure is required to tie physical ports to the orchestration that you built and deployed.

Bind the orchestration

1. In the BizTalk Server Administration console, click the Orchestrations node.

2. Right-click the OrderProcess.MyCompanyOrderProcessing orchestration, and then click Properties.

3. Select the Bindings tab.

4. Under Host, select BizTalkServerApplication in the Host field.

5. Under Bindings, select FromSource for the ReceivePurchaseOrder Inbound Logical Port.

6. Under Bindings, select SendToDestination for the SendPurchaseOrder Outbound Logical Port.

7. Click OK.

8. Right click OrderProcess.MyCompanyOrderProcessing orchestration, and then click Start.

Send a message through the system

In this procedure you create an InfoPath form and upload it to the Windows SharePoint Services Web site. The Windows SharePoint Services adapter will take that message, archive it in the Archive document library, and then send it to the Destination document library. During the processing of this message, Windows SharePoint Services context properties will be accessed that help determine the destination.

Create an InfoPath form to send through the system

1. Open a Web browser and navigate to the URL of the site you created. For example, http://<server_name>/sites/WSSAdapterWalkthrough.

2. In the Quick Launch menu, click InfoPathSolutions.

3. Click the PurchaseOrder file to display the File Download dialog box, and then click Open. InfoPath will load the form.
