SAP常用函数

1、获取月末最后一天日期

DATA LAST_DATE TYPE SY-DATUM.
CALL FUNCTION 'LAST_DAY_OF_MONTHS'
  EXPORTING
    day_in            = sy-datum
  IMPORTING
    last_day_of_month = last_date
  EXCEPTIONS
    day_in_no_date    = 1
    OTHERS            = 2.

 2、提取字符串中的数字

DATA tax_rate_char(5) TYPE c.
DATA tax_rate TYPE I.
tax_rate_char = '  16%'.
CALL FUNCTION 'PREPARE_STRING'
  EXPORTING
    i_valid_chars  = '  0123456789.'
    i_xvalid_check = 'X'
    i_xchar_repl   = 'X'
    i_xtoupper     = 'X'
  CHANGING
    c_string       = tax_rate_char.
tax_rate = tax_rate_char.
