Publishing a Service 
In the case of a separate ITS, templates and MIME files are published on the ITS server; the integrated ITS obtains this data directly from the database at runtime. However, the templates and MIME files must be published on the site INTERNAL. This process is necessary to activate changes to the templates (that is, the changed templates are only used at runtime after publishing).
Caution
Note that by default, no entry is made for the ITS server on which the publishing is to take place. When publishing, you are informed that you must first make a selection for the SAP System. To do this, choose and then, under ITS, enter the desired ITS server. For further information, refer to User Settings
To publish an entire Internet service from the tree display of the object list, proceed as follows:
From the object list, select the relevant service.
Choose Publish Complete service in the context menu.
If an error occurs while the system is publishing the service, a log is generated containing the relevant message texts.
If no errors occur, the system displays the message Object published successfully.
The current status of the object changes after it has been published. For information on how the status of a Web development object is determined, and how you can display its publishing details, see Statuses of Web Development Objects
Once you have published the entire service, you can start the service and thus the Web application.
