    ABAP DICTIONARY

    Field Exits:

    Field exits take you from a screen field with a data element reference to a function module. Field exits can be either global or local.

    Field exit function modules adhere to the following naming convention:

    prefix: FIELD_EXIT_

    name: <data element name>_

    suffix (optional): 0 to 9, A to Z

    Global field exits are not limited to a particular screen. If a global field exit's data element is used on multiple screens, you will branch to a function module from all of these screens once the exit has been activated. Here you can, for example, edit the contents, force a new entry to be made by outputting an error message, or prohibit certain users from proceeding further.

    Local field exits are valid for one screen only. If you assign a screen from a specific program to the data element, then you will only branch to a function module from this screen once the exit has been activated. To be able to allow different functionality on different screens referring to the same data element, you can assign exit numbers to data elements. Each exit number refers to a different function module.

    prefix: FIELD_EXIT_

    name: <data element name>_

    suffix (optional): 0 to 9, A to Z

    Field Exits – It is triggered at field level.

    It is attached at data element

    Specific to one screen only or to all the screen where field appears.

    Field exit is not allowed in SAP version 4.7 and above .

    Example with screen shots for consultants working in

    SAP V 4.6 below version.
