F4_DATE - displays a calendar in a popup window and allows user to choose a date, or it can be displayed read only.
F4_IF_FIELD_VALUE_REQUEST - Use values from a DDIC table to provide a list of possible values. TABNAME and FIELDNAME are required fields, and when MULTIPLE_CHOICE is selected, more than one value can be returned.
HELP_VALUES_GET - F4 help
Code:
PARAMETERS p_grund TYPE t157d-grund.
CALL FUNCTION 'HELP_VALUES_GET'
EXPORTING
fieldname = 'GRUND'
tabname = 'T157D'
IMPORTING
select_value = p_grund.
F4IF_INT_TABLE_VALUE_REQUEST - F4 help that returns the values selected in an internal table. Very handy when programming your very own F4 help for a field.
Code:
data:
begin of t_values occurs 2,
value like kna1-begru,
end of t_values,
t_return like ddshretval occurs 0 with header line.
append o_begru to s_begru.
else.
o_begru = i_begru.
endif.
F4IF_SHLP_EXIT_EXAMPLE - documents the different reasons to use a search help exit, and shows how it is done.
HELP_START - Display help for a field. Useful for doing AT SELECTION SCREEN ON VALUE REQUEST for those fields that do not provide F4 help at the DDIC level.
HELP_VALUES_GET_WITH_TABLE - Show a list of possible values for F4 popup help on selection screens. This function module pops up a screen that is just like all the other F4 helps, so it looks like the rest of the SAP system. Very useful for providing dropdowns on fields that do not have them predefined.
Code:
tables: t001w.
DATA: lc_werks LIKE t001w-werks,
ltab_fields LIKE help_value OCCURS 0 with header line,
BEGIN OF ltab_values OCCURS 0,
feld(40) TYPE c,
END OF ltab_values.
*-- Set up fields to retrieve data
ltab_fields-tabname = 'T001W'.
ltab_fields-fieldname = 'WERKS'.
ltab_fields-selectflag = 'X'.
APPEND ltab_fields.
HELP_START - при настройках как ниже, позволяет вызвать search help не только при нажатии F4, но и enter
