ABAP_SYNTAX
SELECTION-SCREEN PUSHBUTTON $[/$]$[pos$|POS_LOW$|POS_HIGH$](len) button_text

$[VISIBLE LENGTH vlen$]
$[ MODIF ID modid$]
$[ldb_additions$].
ABAP Addition
1 ... $[/$]$[pos$|POS_LOW$|POS_HIGH$](len)
2 ... USER-COMMAND fcode
3 ... VISIBLE LENGTH vlen
What does it do?
This statement creates a pushbutton on the current selection screen. The text on the pushbutton is determined by the content of button_text. The rules that apply to text in the addition COMMENT also apply to button_text. The addition MODIF ID assigns the pushbutton to the modification group modid.
The ldb_additions can only be used in the selection include of a logical database.
Latest notes:
The function module ICON_CREATE can be used to assign an icon, a tooltip, and a text to a pushbutton. The length len of a pushbutton for the internal display of the icon must be set to a sufficient length and the visible length must be modified using VISIBLE LENGTH.
Once the event block in AT SELECTION-SCREEN has been processed, the system usually returns to displaying the selection screen. To exit selection screen processing and continue executing the program, either Execute or Cancel must be chosen. This means pushbuttons on selection screens are intended primarily for use for dynamic modifications to the selection screen rather than to control the program.

• / SELECTION-SCREEN PUSHBUTTON
• POS_LOW SELECTION-SCREEN PUSHBUTTON
• POS_HIGH SELECTION-SCREEN PUSHBUTTON
ABAP Addition
What does it do?
The position of the pushbutton must be specified using this addition. The syntax and meaning are the same as when creating horizontal lines, although in this case len defines the length of the pushbutton in the dynpro of the selection screen. If a pushbutton extends beyond position 83 or a block with a frame, it is truncated on the right.
• USER-COMMAND SELECTION-SCREEN PUSHBUTTON
ABAP Addition
What does it do?
If the addition USER-COMMAND is specified, the pushbutton must be assigned a function code fcode. The function code fcode must be specified directly and can only contain a maximum of 20 characters.
To enable the pushbutton, the statement TABLES must be used to declare an interface work area of the structure SSCRFIELDS from the ABAP Dictionary.
If the user selects the pushbutton on the selection screen, the runtime framework raises the event AT SELECTION-SCREEN and the function code fcode is passed to the component ucomm in the interface work area sscrfields.
Latest notes:
If the function code of a pushbutton corresponds to a function code used in the GUI status of the selection screen, the selection screen processing is affected accordingly.
It is not recommended that the system field sy-ucomm is evaluated instead of sscrfields-ucomm, since this does not guarantee that sy-ucomm is always given the correct value in selection screen processing.
ABAP_HINT_END
• VISIBLE LENGTH SELECTION-SCREEN PUSHBUTTON
ABAP Addition
What does it do?
The addition VISIBLE LENGTH defines the visible length vlen of the pushbutton and its text. The syntax and meaning of this addition are the same as when creating output fields, although a pushbutton is never displayed shorter than the text defined for it.
Example ABAP Coding
Defines and accesses a standalone selection screen 500 with two pushbuttons in an executable program. An icon and a tooltip are created for the second pushbutton.
