Procedure

As delivered, the standard system enables users to render certain infotype fields invisible, or to make input for other infotype fields mandatory. To this end, users can modify the Infotype Screen Control table (T588M) accordingly, either through corresponding country-specific Customizing activities, or, in Customizing for Personnel Administration (PA-PA), by choosing  Customizing User Interfaces Change Screen Modifications .

The Infotype Screen Control table is considered to be part of the user interface, rather than part of the business logic. Nonetheless, the Infotype Screen Control table obviously introduces implicit value restrictions, as described above. Moreover, it is important to remember that the Infotype Screen Control table imposes restrictions that are not processed during direct input, exactly like the implicit restrictions already described. Therefore, in the event that you encounter such restrictions, you are required to consider them in your business logic as well.
