在ALV列表中显示一个标签

Question

目前我的程序写出的结果，但我希望我可以输出到一个ALV列表。我可以使用reuse_alv_list_display函数吗?

下面是我目前为止的代码:

REPORT  Z_TRANSFORMER_TOOL_BATCH.
TABLES zfit_map_account.
TYPES: BEGIN OF t_account,
        saknr TYPE saknr,
        txt20 TYPE txt20,
        zznew TYPE new_saknr,
        ntx20 TYPE zntx20,
       END OF t_account.
DATA: gwa_account TYPE t_account.
DATA: gt_account TYPE TABLE OF t_account.
SELECT saknr txt20 zznew ntx20
FROM zfit_map_account
INTO gwa_account
WHERE zznew = '1010101998'.
APPEND gwa_account TO gt_account.
ENDSELECT.
Loop at gt_account INTO gwa_account.
  Write :/ gwa_account-saknr, gwa_account-txt20, gwa_account-zznew, gwa_account-ntx20.
ENDLOOP.

一个简单的方法是使用cl_salv_table类。你可以这样做来替换整个循环部分

DATA alv TYPE REF TO cl_salv_table.
TRY.
      cl_salv_table=>factory(
        IMPORTING
          r_salv_table = alv
        CHANGING
          t_table      = gt_account ).
    CATCH cx_salv_msg INTO message.
      " handle error
  ENDTRY.

alv->display( ).
