SAP 中strlen()只能计算字符串的个数，不能计算含有中文字符串的长度，如字符串“SAP大波霸”，strlen("SAP大波霸") = 6,其实真实长度为3+3*2 = 9。我们可以通过cl_abap_list_utilities=>dynamic_output_length来精确获取字符串长度，下面我写了一个截取字符串长度的函数，供参考：

FUNCTION zotfm001.*"----------------------------------------------------------------------*"*"本地接口：*"  IMPORTING*"     VALUE(I_STRING) TYPE  STRING*"     VALUE(I_STRLEN) TYPE  I*"  EXPORTING*"     VALUE(E_STRING1) TYPE  STRING*"     VALUE(E_STRING2) TYPE  STRING*"----------------------------------------------------------------------  DATA:lv_char TYPE string,       lv_len  TYPE i,       lv_st1  TYPE i,       lv_st2  TYPE i,       lv_str  TYPE i.  CHECK i_string IS NOT INITIAL AND i_strlen IS NOT INITIAL.  lv_str = strlen( i_string ).  DO.    IF lv_str >= sy-index.      lv_char = i_string+0(sy-index).      CALL METHOD cl_abap_list_utilities=>dynamic_output_length        EXPORTING          field = lv_char        RECEIVING          len   = lv_len.      IF lv_len >= i_strlen.        e_string1 = lv_char.        lv_st1 = strlen( lv_char ).        lv_st2 = lv_str - lv_st1.        e_string2 = i_string+lv_st1(lv_st2).        EXIT.      ENDIF.    ELSE.      e_string1 = i_string.      e_string2 = "".      EXIT.    ENDIF.  ENDDO.ENDFUNCTION.
