Step 5: Activate the ABAP Program and Publish the ITS Service 
The final step of making ITS services with flow logic executable in the integrated ITS is to activate the ABAP program and publish the Internet service for use in the integrated ITS.
You have successfully performed the following steps:
Open the ABAP Workbench (transaction SE80).
Select the program to be activated, and choose the Activate option from its context menu.
In transaction SE80, switch back to your Internet service.
Select the service and choose from the context menu.
Ensure that you publish to SITE INTERNAL.
A message in the status line shows whether the publishing to the INTERNAL site was successful.
The program is activated for use and the Internet service is published on the integrated ITS.
