i login in the www.se37.com and enter HELP_VALUES_GET_WITH_TABLE

in the FM input field, and the website popup 'there is no documentaton for function module HELP_VALUES_GET_WITH_TABLE'

is the FM HELP_VALUES_GET_WITH_TABLE not used frequently?

refer from the documentation in the t-code se37.

You can use the below code:

DATA : v_dataum TYPE sy-datum.

CALL FUNCTION 'F4_DATE'

EXPORTING

DATE_FOR_FIRST_MONTH = SY-DATUM

• DISPLAY = ' '

• FACTORY_CALENDAR_ID = ' '

• GREGORIAN_CALENDAR_FLAG = ' '

• HOLIDAY_CALENDAR_ID = ' '

• PROGNAME_FOR_FIRST_MONTH = ' '

IMPORTING

SELECT_DATE = v_datum

• SELECT_WEEK = SELECT_WEEK

• SELECT_WEEK_BEGIN = SELECT_WEEK_BEGIN

• SELECT_WEEK_END = SELECT_WEEK_END

• EXCEPTIONS

• CALENDAR_BUFFER_NOT_LOADABLE = 1

• DATE_AFTER_RANGE = 2

• DATE_BEFORE_RANGE = 3

• DATE_INVALID = 4

• FACTORY_CALENDAR_NOT_FOUND = 5

• HOLIDAY_CALENDAR_NOT_FOUND = 6

• PARAMETER_CONFLICT = 7

• OTHERS = 8

.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.
