Switchable Units
Definition
In the context of the Switch Framework, development objects can be of two types: switchable and non-switchable. Both types can be assigned to switches. The behavior of switchable objects in the system depends on the switch settings.
Structure
Below is the list of switchable units:
● Packages
You can switch the following repository objects by assigning them to a package:
○

● Screen fields
You can assign a switch to each
screen
field when you define it in the Screen
Painter. A screen field can be used only
when the switch is switched on. By assigning a switch to a screen field, you
also assign the corresponding FIELD
statements of
the screen flow logic. The FIELD statements are only taken into
account if the switch is switched on.
When you define a screen field, you should specify whether the corresponding screen elements are to be hidden when the switch is switched on. In this way, you can replace existing screen fields with others.
The program SFW_FIND_SWITCHED_ELEMENTS can be used to search switched UI elements by business function. Its scope are the UI elements assigned in Screen Painter.
● Calling modules
You can link the MODULEstatement of the
screen flow
logic to a switch
directly through the
SWITCH
addition.
Such a MODULE
statement is
only taken into account if the switch is switched on.
● Function codes
You can assign a switch to a
function
code when defining the function code in
the Menu Painter.
● Maintenance views and view clusters
You can assign a switch to any field of a
maintenance
view when you define the view in the ABAP
Dictionary. All fields that you want to switch need to be part of the maintenance view. No appends are
used for the switchable parts of a maintenance view.
The same applies to
view
clusters. You can specify one switch for each view to
control its visibility. All views that you want to
switch need to be part of
the view cluster.
● Nodes of an IMG structure
You can assign a switch to each node of an IMG
structure in the
IMG Structure
Maintenance. An IMG structure node is displayed only when the switch is switched
on.
● Nodes of an area menu
You can assign a switch to each node of an area menu
in the
Area Menu
Maintenance. An Area Menu node is displayed only when the switch is switched
on.
