You perform the following steps to create actions and assign the interfaces for message exchange to them.
First, define the action CancelFlightBookingOrder, which the travel agency uses to send the cancellation to the airline.
...
1. Position the cursor on the application component Agency.
2. In the context menu, choose Create Action.
3. On the Create a New Action screen, under Type of Usage, select the Internal radio button.
4. Choose Continue.
5. In the Name field, enter CancelFlightBookingOrder.

The software component version and namespace are already entered.
6. In the Description field, enter Cancel flight booking order.
7. Choose Finish.
8. The system opens the Display Action object editor.
9.
Switch to change
mode. To do this, choose Switch Between Display and Edit
Modes (
) in the object editor toolbar.
10.
In the Outbound
Interfaces frame, insert a
new line. To do this, choose Insert Line Below Selection (
).
11. In the Object Type column, select Service Interface in the dropdown list box.
12. Use the input help () for the Namespace column to select your namespace http://MyTutorial<ID>.

20. Save the action.
You perform the following steps to insert the action CancelSingleFlightBooking into the process integration scenario. This action is used to cancel a flight booking with an airline.
The demo examples already contains this action. Therefore, you do not need to create it separately, but can reuse it.

1. Position the cursor on the application component Airline (diagonally underneath the action CancelFlightBookingOrder that you created earlier), call the context menu, and choose Insert Action.
2. On the Choose Action screen, expand the software component version SAP BASIS 7.10 and the namespace http://sap.com/xi/XI/Demo/Airline.
3. Select the action CancelSingleFlightBooking.
