The table of possible events per list type can be initialized using the module REUSE_ALV_EVENTS_GET.

You can display the names of the constants in the type pools SLIS which represent the individual events using the individual test function in the function module
REUSE_ALV_EVENT_NAMES_GET. Only events with a form routine name are processed.

The table structure contains the fields:

IT_EVENTS-NAME
Name of the Callback event.
Possible Callback events:
Action
USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
RS_SELFIELD TYPE SLIS_SELFIELD
Process actions on the list
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
PF_STATUS_SET USING RT_EXTAB TYPE SLIS_T_EXTAB
If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
The STANDARD status of the function group SALV should be used as a template for a user-specific status.
As this is a frequently-used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
ITEM_DATA_EXPAND USING RS_SELFIELD TYPE SLIS_SELFIELD
RFLG_ALL TYPE C
Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT.
Exit for passing item entries (ITEM table) for a header record which was expanded interactively by the user.
RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header which is to be expanded.
RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that entries are not repeated in the item table.
RS_SELFIELD is initial in this case.
CALLER_EXIT USING RS_DATA
Is called at the beginning of the function module to make special settings. It is not usually used.
List processing events
IMPORTANT: The application Callback routine must not manipulate the internal output table and/or its header record. This restriction applies to all Callbacks which are called in the list output and run under the 'List processing events'.
TOP_OF_LIST no USING parameter
Information output at the start of the list
END_OF_LIST no USING parameter
Information output at the end of the list
TOP_OF_PAGE no USING parameter
Equivalent to the list processing TOP-OF-PAGE event
END_OF_PAGE no USING parameter
Not available for hierarchical-sequential lists.
Information output at the end of a page. This is only called for printing.
TOP_OF_COVERPAGE no USING parameter
The selection information and list status are output together (if they exist) on a separate page by default. See also the documentation of the parameters:
IS_PRINT-NO_COVERPAGE
IS_PRINT-NO_PRINT_SELINFOS
IS_PRINT-NO_PRINT_LISTINFOS
IS_LAYOUT-GET_SELINFOS
The user can format the header area of the 'cover page' himself or herself by specifying a Callback routine for this event.
END_OF_COVERPAGE no USING parameter
Analogously to TOP_OF_COVERPAGE the user can add other information to the information output by ALV (selection information, list status) at this event.
FOREIGN_TOP_OF_PAGE no USING parameter
The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
FOREIGN_END_OF_PAGE no USING parameter
The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
BEFORE_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
AFTER_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
Internal use only
LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
R_INDEX LIKE SY-TABIX
R_INDEX_ITEM LIKE SY-TABIX
R_INDEX_SUM LIKE SY-TABIX
IT_EVENTS-FORM
Name of the form routine which should be called in the calling program at the event.
