ABAP字符串反转 and 寻找字符所在位置 and 根据数量汇总时把数量转为非数值类型

1.字符串反转 and 寻找字符所在位置

 LOOP AT gt_wlmc ASSIGNING FIELD-SYMBOL(<fs_wlmc>).  "遍历内表
    <fs_wlmc>-matnr = <fs_wlmc>-matnr+(8).
    DATA: l_output TYPE char50,
          v_off2   TYPE i,
          str      TYPE i,
          str2     TYPE i.
    CALL FUNCTION 'STRING_REVERSE'   "反转字符窜
      EXPORTING
        string    = <fs_wlmc>-zcailiao
        lang      = ''
      IMPORTING
        rstring   = l_output
      EXCEPTIONS
        too_small = 1
        OTHERS    = 2.
    IF sy-subrc <> 0.
* Implement suitable error handling here
    ENDIF.

    str = strlen( l_output ).
    FIND '_' IN l_output MATCH OFFSET v_off2.   "反转后找最后一个字符串出现的位置
    str2 = str - v_off2 - 1.
    IF sy-subrc = 0 AND str2 <> 0 .
      <fs_wlmc>-zcailiao = <fs_wlmc>-zcailiao+(str2).
    ELSE.
      <fs_wlmc>-zcailiao = '' .
    ENDIF.
  ENDLOOP.
  SORT gt_wlmc BY matnr.

  READ TABLE gt_zdz INTO DATA(gs_tou) WITH KEY zdzdh = gs_dzd-zdzdh .
  READ TABLE gt_zfp INTO DATA(gs_zfp) WITH KEY zdzdh = gs_dzd-zdzdh .

  DATA lv_string TYPE string.
  LOOP AT gt_zdz ASSIGNING FIELD-SYMBOL(<fs_row>).  "遍历内表
    DATA :lv_number TYPE i,
          v_off     TYPE i.
    READ TABLE zsuima INTO DATA(gs_zsuima) WITH KEY mwskz = <fs_row>-zmwskz.
    IF sy-subrc = 0 .
      FIND '%' IN gs_zsuima-text1 MATCH OFFSET v_off.  "第一个%出现的位置
      IF sy-subrc = 0.
        lv_number = gs_zsuima-text1+(v_off).
      ENDIF.
    ENDIF.

    <fs_row>-znetpr = <fs_row>-znetpr * ( 1 + ( lv_number / 100 ) ).

    IF <fs_row>-zmatnr <> ''.
*          lv_string = strlen( <fs_row>-zmatnr ) - 3 .
      <fs_row>-zmatnr = <fs_row>-zmatnr+(8).
    ENDIF.

  ENDLOOP.

2.根据数量汇总时把数量转为非数值类型

TYPES:
    BEGIN OF tt_zdz,
      zdzdh  TYPE ztmm019a-zdzdh,
      zbckh  TYPE ztmm019a-zbckh,
      zmatnr TYPE ztmm019a-zmatnr,
      znetpr TYPE ztmm019a-zdzdh,
      zmenge TYPE ztmm019a-zmenge,
      zhsje  TYPE ztmm019a-zhsje,
    END OF tt_zdz.

  DATA:gtt_zdz TYPE STANDARD TABLE OF tt_zdz,
       gss_zdz TYPE tt_zdz.

 LOOP AT gt_zdz INTO DATA(gs_zdz).    "单价数量类型转字符类型汇总
    MOVE-CORRESPONDING gs_zdz TO gss_zdz.
    COLLECT gss_zdz INTO gtt_zdz.
    CLEAR gs_zdz.
    CLEAR gss_zdz.
  ENDLOOP.
  SORT gtt_zdz BY zbckh.

znetpr2    TYPE ztmm019a-znetpr. "定义一个数字类型，把字符串类型转为数值类型
 znetpr2 = gss_zdz-znetpr.
