Publishing ITS Services 
You can access ITS services using the integrated ITS only, if besides the activation of the services with transaction SICF the service has also been published. As does the standalone ITS, the integrated ITS also offers a publication mechanism. The site INTERNAL, which is automatically available (without maintaining tables IACORDES and IACORSITE), is used for this purpose.
Publish the service as described under Publishing Services to site INTERNAL.
Caution
After an import of ITS objects, they are automatically published to site INTERNAL. To stop this, you must maintain the site in table IACORSITE to switch off publishing in the import reprocessing.
The service can now be executed (see also Testing the HTTP Request Handler).
