User-Specific ChangesLocate this document in the navigation structure

Use

To change the layout and the logon process according to your special requirements, you can make user-specific changes in addition to the settings that are possible on the configuration screen.

Process

  • Create a new class that is a subclass of CL_ICF_SYSTEM_LOGIN.

  • You change the layout of the logon screen by overwriting the htm_login method in the new class.

  • To modify the screen for the password change, overwrite the htm_change_passwd method.

    Note

    To ensure that the entries made are forwarded to the relevant screens and to trigger the corresponding events for the transfer of the results, it is necessary for you to use default constants and attributes for form names, input field names, event names and script functions. The constants and attributes that should be used depend on the logon functionality to be implemented.
