i.e importing and exporting parameters.

Based upon the importing and exporting parameters write the

custom code.

Menu exit:-

This exit is use to add custom menus to the standard menu bar.

Each menu exit is identified by + symbol.

A menu exit is use to add custom menu and function module exit is

use to add the abap logic for the corresponding menu exit.

This exit is use to add custom sap screen to the standard sap

screen is called screen ecit.

All the screen exits will be of type subscreen.

Each subscreen is identified by screen no

Double click on the screen no and create a screen of type

on sap screen. This are absolete in sap.

Sap does not support this.

Project




Overview

Project:-

The project is a group of enhancements.

Each enhancement is group of exits i.e.function module exit,

screen exit, menu exit.

A project must be created so that the enhancements which areavailable under a project will move into active state and then our

coding will be executed .
