ABAP 常用日期函数总结

WEEK的函数：function group：CADA

1．计算两个日期间的工作天数，即除双休日之外的天数

DATE_CONVERT_TO_FACTORYDATE HR_HK_DIFF_BT_2_DATES

2．根据系统当前时间找到上月的第一天和最后一天。

CALL FUNCTION 'FIMA_DATE_CREATE'

EXPORTING

i_date = sy-datum * I_FLG_END_OF_MONTH = ' ' * I_YEARS = 0 I_MONTHS = '-1' * I_DAYS = 0 * I_CALENDAR_DAYS = 0 I_SET_LAST_DAY_OF_MONTH = 'X' IMPORTING

E_DATE = lastdate. * E_FLG_END_OF_MONTH =

* E_DAYS_OF_I_DATE = .

其中，lastdate为上月最后一天。

Firstday是上月第一天

Concatenate lastdate+(6)'01' into firstday.

3．当天是当年的第几周

DATE_GET_WEEK

4．得到该周第一天

Week_get_first_day

5．查找当前月份以前的月份（比如现在是4月份，如果我需要知道六个月以前的月份）

ccm_go_back_months rp_calc_date_in_interval

6．获取两日期之间天数函数：

fima_days_and_months_and_years

7．取得当月的第一天和最后一天

Concatenate sy-datum(6)'01' into so_date-low.

Call function'BKK_GET_MONTH_LASTDAY'

EXPORTING

i_date = SY-DATUM * IMPORTING

E_DATE = so_date-high.

So_date-sign = 'I' . So_date-option = 'BT'. Append so_date.

8．Rp_calc_date_in_interval 年月日加减 9．DATE_CHECK_PLASIBILITY 日期有效性检查

10．SD_DATETIME_DIFFERENCE 两日期做差

11．DATE_CONVERT_TO_FACTORYDATE 把输入日期转为工厂日历日期 12．MONTH_NAMES_GET 获得所有的月和名字

13．F4_DATE 弹出一个窗口显示一个日历允许用户选择一个日期 14．RP_LAST_DAY_OF_MONTHS 获得一个月的最后一天 15．FIRST_DAY_IN_PERIOD_GET 获得期间首日 16．LAST_DAY_IN_PERIOD_GET 获得期间末日

17．获得两个日期的年数

CALL FUNCTION 'HR_99S_INTERVAL_BETWEEN_DATES'

EXPORTING

BEGDA = gdat endda = sy-datum * TAB_MODE = ' ' * IMPORTING

* DAYS = * C_WEEKS = * C_MONTHS =

C_YEARS = l_age * WEEKS = * MONTHS = * YEARS = * D_MONTHS = * MONTH_TAB = .

18．关于星期的函数

CALLFUNCTION 'GET_WEEK_INFO_BASED_ON_DATE' EXPORTING

DATE = SY-DATUM

IMPORTING

WEEK = MONDAY = SUNDAY =

19．输入日期，显示星期几

CALL FUNCTION 'DAY_IN_WEEK'

EXPORTING

datum =

WOTNR = 对应日期星期几 IMPORTING

20．弹出选择周的对话框

AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_week-low.

PERFORM getweek CHANGING s_week-low.

*&---------------------------------------------------------------------*

*& Form getweek

*&------------------------------------------------------------ FORM getweek CHANGING p_week. DATA: begin_date TYPE d.

CALL FUNCTION 'POPUP_CALENDAR_SDB' EXPORTING

* SEL_DAY = sel_week = 'X' * SEL_MONTH = * SEL_INTERVAL = * DAY_INFO =

* SEL_ONLY_MARKED_DAYS =

focus_day = sy-datum * IMPORTING

begin_date = begin_date * END_DATE =

CALL FUNCTION 'GET_WEEK_INFO_BASED_ON_DATE' EXPORTING

date = begin_date IMPORTING

week = p_week.

* MONDAY = * SUNDAY =

ENDFORM. \

21．只显示年月，但要有日期的search help.

PARAMETERS: p1(6) TYPE c.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p1.

DATA: l_date 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 = l_date * SELECT_WEEK = * SELECT_WEEK_BEGIN = * 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.

p1 = l_date+0(6).

*检查日期的合理性

CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'

EXPORTING

date = bkdf-dbbdt \周期性分录的凭证抬头补充周期性分录凭证开始日期 EXCEPTIONS

plausibility_check_failed = 1 OTHERS = 2.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4. ENDIF.

22．判断是不是时间 TIME_CHECK_PLAUSIBILITY 23．得到当前的财政年 GET_CURRENT_YEAR

24．查看某日期的属性，包括该日期是周几，第几天，是不是公共假日，需要输入国家日历 DAY_ATTRIBUTES_GET
