Logon Data for Cache Notifications Tag Page

This tab page shows whether a business system supports communication using the Web service runtime.

It displays the following information:

  • Whether cache notifications can be sent to the back-end system

  • The service user that can send the cache notifications to the back-end system

    To send cache notifications, you must select the Business System Communicates Using Web Service Runtime checkbox.

    If you want to restrict sending of cache notifications to a particular service user and password, you can specify this here.


    Note that business systems can only communicate directly with each other using the Web service runtime if you have made the setting to allow cache notifications to be sent.


    The central Web services configuration is only possible for business systems with release Web AS ABAP 7.10 or higher. The tab page with the logon data for cache notifications is only displayed for these business systems.
