The structure SCREEN
Most components of the structure SCREEN
from ABAP Dictionary correspond to the attributes of a screen element on a dynpro.
Data objects with the data type SCREEN can be used as a work area in the following ABAP statements:

in LOOP AT SCREEN , to read the screen element properties of a dynpro,

in MODIFY SCREEN , to modify the screen element properties of a dynpro.

The following table shows the components of SCREEN , their assignment to the field properties in the dynpro, and the possible values.
Component Length Type Attribute
Value Meaning
name 132 c Name name Name
group1 3 c Group 1 id1 Modification Group
group2 3 c Group2 id2 Modification Group
group3 3 c Group3 id3 Modification Group
group4 3 c Group4 id4 Modification Group
required 1 c Mandatory field 0 , 1
2 Mandatory or recommended field
input 1 c Input 0 , 1 Input-ready field
output 1 c Output 0 , 1 Display field
intensified 1 c Light 0 , 1
Highlighted field
invisible 1 c Invisible 0 , 1
Invisible element
length 1 x VisLg ... Field length
active 1 c - 0 , 1 Active field
display_3d 1 c Two-dimensional 0 , 1
Frame
value_help 1 c Input help 0 , 1 , 2 Input help button
request 1 c - 0 , 1 Input exists
values_in_combo 1 c dropdown list box 0 ,
1 Input help available

The name component contains the name of the current dynpro field in the loop. The components group1 to group4 can contain three figure identifiers id1 to id4 , which were assigned to the current screen element when it was defined. These identifiers allow the screen elements to be grouped together in up to four different modification groups
. These can be queried in logical expressions in the statement block after LOOP AT SCREEN , in order to process multiple screen elements in the same way.
The remaining components of the structure SCREEN (apart from
request ) show the display properties of the current screen element. With the exception of length , they can have the value 0 or 1, where content 1 means "active" and content 0 means "inactive". In addition, required and value_help can also have the value 2:

With required , value 2 means a recommended field which is displayed on the screen in the same way as a mandatory field (value 1) but a check is not performed.

With value_help , value 2 means that the input help button is always displayed, whereas value 1 means that the button is only displayed if the cursor is positioned on the dynpro field.

Except for active and request , all components of the structure SCREEN correspond directly to an attribute of the current screen element.

The active component does not have a corresponding attribute. A change to its content using MODIFY SCREEN

influences the input , output and invisible attributes, and correspondingly the input , output and
invisible components of the structure SCREEN .

The request component is set to value 1 by the runtime environment if the event PAI occurs, provided that user input exists has been entered into the dynpro field.
