Function group can be defined it as collection of Function
modules. This Function groups are presents in the Packages
where we can create in the SE38. So,that all packages are
consists in the Function Groups.All function groups are
consists Function Modules.This function modules are created
at enhancements/Exists. These are 4 types i.e are

1.Menu Exist
2.Screen Exist
3.Field Exist
4.Function Exist

The above are created at Customizing the screens with
menus,screens and fields.

If the screen is having the customization or not? for that
we are using press F1 button and click on the Technical
Information button. So, that we can identify the
Customization field has "+PGE" code. If it is present we
can do the menu exist.

If this case we can have "Function Exist" and "Menu Exist"
is done.

Some of them does't have Menu,Screen,Field.So, in this case
only one "Function Exist" done.(Means only we can write the
program).


All the best my well wishers..............
