Extras
1. ... [/]pos|POS_LOW|POS_HIGH
2. ... USER-COMMAND fcode
3. ... VISIBLE LENGTH vlen
Effect
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 also apply to button_text
in the additionCOMMENT.
The addition MODIF ID assigns the pushbutton to the
modification group modid zu.
The additions ldb_additions can only be used in the selection include for a
logical database.
Notes
-
You can use the function module ICON_CREATE to assign an icon, a
quick info text and a corresponding
text to a pushbutton. When you do this, you must specify an adequate length
lenfor the pushbutton so that the icon can be displayed internally and adjust the visible length withVISIBLE LENGTH. -
Once the event block in
AT SELECTION-SCREENhas been processed, the system usually returns to displaying the selection screen. To exit selection screen processing and continue executing the program, you can only choose Execute or Cancel. This means pushbuttons on selection screens are intended primarily for use for dynamic modifications to the selection screen rather than to control the program.
Addition 1
... [/]pos|POS_LOW|POS_HIGH
Effect
You must specify the position of the pushbutton using this addition. The syntax and meaning of are the same as when creating
horizontal lines, although in this case, len defines the length of the pushbutton on the selection
screen. If a pushbutton extends beyond position 83 or beyond the edge of a
block with a frame, it is cut off at the right hand side.
Addition 2
... USER-COMMAND fcode
Effect
If you specify the USER-COMMAND addition, 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.
Before you can work with the pushbutton, you must specify a TABLES statement to declare an
interface work area for the structure SSCRFIELDS from the ABAP Dictionary.
If the user selects the pushbutton on the selection screen, the runtime environment triggers the event
AT SELECTION-SCREEN
and the function code fcode is transferred to the ucomm component in the interface work area sscrfields.
Note
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 influenced accordingly.
Addition 3
... VISIBLE LENGTH vlen
Effect
The VISIBLE LENGTH addition defines the visible length vlen of the pushbutton and your text. The syntax and meaning of this addition are the same as when creating
output fields, although a pushbutton is never displayed as shorter than the text defined for it.
Example
Define and access a stand-alone
selection screen 500 with two pushbuttons in an executable program. An icon and a quick info text are created for the second pushbutton.
