The addition USING SELECTION-SCREEN specifies the
selection screen and
VIA SELECTION-SCREEN specifies whether it is displayed. The additions selscreen_parameters provide values for the parameters, selection criteria, and the free selection of the called selection screen.
The values are passed to the selection screen between the events
INITIALIZATION and AT SELECTION SCREEN OUTPUT. The following hierarchy applies to the passing of the values:
First, the selection screen variant
of the addition USING SELECTION-SET is passed and this sets all parameters and selection criteria to the values of the variant. The values previously set in the called program are overwritten.
The values of the table of the addition WITH SELECTION-TABLE are then passed. All parameters and selection criteria are overwritten accordingly.
Finally, the values of the additions WITH sel value are passed. All parameters
and selection criteria are overwritten accordingly. If the addition WITH sel value
is used more than once for the same parameter, this parameter is overwritten with the last specified value. If the addition WITH sel value is used more than once for the same
selection criterion, a
selection table with the corresponding number of rows is passed.
Free selections are filled independently of this hierarchy.
Notes
The options for parameter passing enable a selection screen to be viewed as a parameter interface of an
executable program. This applies in particular to background
selection screen processing
and to parameters and selection criteria defined without screen elements using the addition NO-DISPLAY
When data is passed, any adjustments made to the screen format, such as abbreviations or the execution of
conversion routines,
should not be executed for fields for which there are no screen elements on the selection screen. This
applies to all parameters and selection criteria defined with NO DISPLAY. It also applies to all rows in a selection table with the exception of the first row.
The additions selscreen_parameters only work the first time the called program
is executed. If a selection screen is displayed in the called program, the runtime environment calls
the program again after it ends. This replaces the values specified in selscreen_parameters with the previous input values.
Addition 1
... USING SELECTION-SCREEN dynnr
Effect
This addition defines which selection screen is called. dynnr is a data object that must contain the
dynpro number of a selection screen defined in the called program when the statement SUBMIT is executed.
If the addition USING SELECTION-SCREEN is omitted or the dynpro number 1000
is entered, the standard selection screen is called. If no standard selection screen is defined in the called program, no selection screen is called.
If a dynpro number other than 1000 is entered in the addition USING SELECTION-SCREEN,
the corresponding standalone selection screen is called. If no selection screen with this dynpro number is defined in the called program, a non-handleable exception is raised.
Addition 2
... VIA SELECTION-SCREEN
Effect
If this addition is specified, the selection screen is displayed on the screen. Otherwise, background selection screen processing takes place. In background selection screen processing, the
selection screen events are raised without the selection screen being displayed.
