Click on the port surface again (now on the right side) and select the "New Configured Port" option again. The wizard will show up again, click Next. On the next screen, type srpGetCustomer as the port name, and click Next. On the next screen, select the "Use Existing Port Type" option and select the "OrderManager.SQLExec" port type.
