重复计数相似的行值

Question

 IF ls_th_sum_lab_ndt IS not INITIAL.
        ls_th_sum_lab_ndt-ndt_flag = 'X'.
        ls_th_sum_lab_ndt-zwc_cat = 'NDT'.
if there are more than 2 zwc_cat that equal to NDT change the other one to MH

        APPEND ls_th_sum_lab_ndt TO gt_th_sum_lab_ndt.
      ENDIF.

基本上我想做什么：

如果ls_th_sum_lab_ndt-zwc_cat=MH将第二行设置为MH，则更新ls_th_sum_lab_ndt-zwc_cat="NDT" >2

先谢谢您！

Answer 1

尝试一下：

DATA: lv_count type i,
      lv_index type sy-tabix.
...
LOOP AT gt_th_sum_lab_ndt INTO ls_th_sum_lab_ndt WHERE zwc_cat = 'NDT'.
  lv_count = lv_count + 1.
  if lv_count >= 2.
    lv_index = sy-tabix.
    exit.
  endif.
ENDLOOP.

CHECK lv_count >= 2.
READ TABLE gt_th_sum_lab_ndt INTO ls_th_sum_lab_ndt INDEX lv_index.
ls_th_sum_lab_ndt-zwc_cat = 'MH'.
MODIFY gt_th_sum_lab_ndt FROM ls_th_sum_lab_ndt INDEX lv_index.

希望有帮助。
