follwing is list of events :

Only events with a form routine name are processed.

The I_EVENTS table returns with the following possible constants:

1. Slis_ev_item_data_expand TYPE slis_formname VALUE 'ITEM_DATA_EXPAND'.

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 that was expanded interactively by the user.

2. Slis_ev_reprep_sel_modify TYPE slis_formname VALUE 'REPREP_SEL_MODIFY'.

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 that 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.

3. Slis_ev_caller_exit_at_start TYPE slis_formname VALUE 'CALLER_EXIT'.

Is called at the beginning of the function module to make special settings. It is not usually used.

4. Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.

As this is a frequently-used Callback event, the form routine can also be passed directly in the interface by passing the user command in the IMPORTING parameter I_CALLBACK_USER_COMMAND.

5. Slis_ev_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'.

Equivalent to the list processing TOP-OF-PAGE event.

6. Slis_ev_top_of_coverpage TYPE slis_formname VALUE 'TOP_OF_COVERPAGE'.

The selection information and list status are output together (if they exist) on a separate page by default

7. Slis_ev_end_of_coverpage TYPE slis_formname VALUE 'END_OF_COVERPAGE'.

Analogously to TOP_OF_COVERPAGE the user can add other information

to the information output by ALV (selection information, list status) at this event.

8. Slis_ev_foreign_top_of_page TYPE slis_formname VALUE ‘FOREIGN_TOP_OF_PAGE'.

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.

9. Slis_ev_foreign_end_of_page TYPE slis_formname VALUE 'FOREIGN_END_OF_PAGE'.

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.

10. Slis_ev_pf_status_set TYPE slis_formname VALUE 'PF_STATUS_SET'.

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.

11. Slis_ev_list_modify TYPE slis_formname VALUE 'LIST_MODIFY'.

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.

12. Slis_ev_top_of_list TYPE slis_formname VALUE 'TOP_OF_LIST'.

Information output at the start of the list

13. Slis_ev_end_of_page TYPE slis_formname VALUE 'END_OF_PAGE'.

Information output at the end of a page. This is only called for printing.

14. Slis_ev_end_of_list TYPE slis_formname VALUE 'END_OF_LIST'.

Information output at the end of the list

15. Slis_ev_after_line_output TYPE slis_formname VALUE 'AFTER_LINE_OUTPUT'.

Output information after each output line. Should only be used in justified cases because it costs a lot of performance.

16. Slis_ev_before_line_output TYPE slis_formname VALUE 'BEFORE_LINE_OUTPUT'.

Output information before each output line. Should only be used in justified cases because it costs a lot of performance.

17. Slis_ev_subtotal_text TYPE slis_formname VALUE 'SUBTOTAL_TEXT'.

This event table (I_EVENTS) is now checked with the desired constants. If the desired constant is found, then the corresponding field for the FORM NAME is populated with the name of the routine containing the corresponding event.
