Flow of an Executable Program
SUBMIT loads the called program in a separate
internal session and starts a series of processes in the
ABAP runtime environment that trigger events and actions in the called program in the following order:
DEFAULT in the statements
are passed to the relevant data objects. The start values of all other data objects are set before
is called if it contains at least one input field or button. If no explicit selection screen is specified, the standard selection screen is called. Complete
selection screen processing
is performed. After the selection screen processing, the program flow is either continued or ended,
depending on the last user action on the selection screen. Before the first event of the selection screen
AT SELECTION-SCREEN OUTPUT, the values specified in
selscreen_options are passed.
GET events, if the called program is associated with a
If the basic list is empty, the program is exited..
If the basic list is a spool list, it is sent to the SAP spool system and the program is exited.
EXPORTING LIST TO MEMORY is specified in
list_options, the basic list is stored in the
ABAP Memory and the program is exited.
Otherwise, the basic list is a screen list and is displayed on the screen. User actions on a displayed screen list trigger list events. The program is exited when the user exits the list display.
If a selection screen displayed in step 4, the runtime environment calls the called program again after the basic list has been exited. During this new call, the runtime environment supplies the parameters, the selection criteria, and the dynamic selections of the selection screen between the events
AT SELECTION-SCREEN OUTPUT with the previous input values (other settings, such as whether
the tabstrip page was active, are not passed). The program call is not complete until the user exits
the selection screen processing by choosing Back, Exit, or Cancel.

If the called program is associated with a logical database, the system calls the relevant subroutines of the
database program for the steps listed above. For information, see
Logical Databases - Associations with Executable Programs.
