显示内部表? [英] Display an internal table?

问题描述

我必须从表格中读取一些数据并显示出来.程序启动了，但我不知道如何显示我选择的任何数据.我想把它摆成一张桌子.

I have to read some data from a table and display it. The program starts but I don't know how to display any of the data I've selected. I want to put it out as a table.

老实说，我什至不知道以下代码是否正确.

I honestly don't even know if the following code is correct.

REPORT ZT_THIEMANN_TEST.

types : begin of ts_output,
          object_id  type CRMD_ORDERADM_H-object_id,
          created_by type CRMD_ORDERADM_H-created_by,
        end of ts_output,
        tt_output type table of ts_output.

PARAMETERS Mel_Nr TYPE CRMD_ORDERADM_H-Object_ID obligatory.

data gt_output type tt_output.

START-OF-SELECTION.

SELECT cm~object_id cm~created_by
from CRMD_ORDERADM_H as cm
into corresponding fields of table gt_output
where cm~object_id like Mel_Nr.

推荐答案

正如 Sandra 所说，您可以使用调试器检查您的代码/选择是否有效.

As Sandra said, you can check if your code/the select works by using the debugger.

您可以用不同的方式输出数据，但最简单的方法是使用 CL_SALV_TABLE 类.在不添加任何附加功能(例如标题、工具栏按钮、排序、热点等)的情况下，以下代码是您如何使用 oo alv 网格显示数据的方法.

You can output data different ways, but the easiest is using the class CL_SALV_TABLE. Without adding any additional features (such as a title, toolbar buttons, sorting, hotspots, etc.), the below code is how you can display your data using the oo alv grid.

...

DATA: go_alv       TYPE REF TO  cl_salv_table,
      gx_salv_msg  TYPE REF TO  cx_salv_msg.

...

  TRY.
      cl_salv_table=>factory(
      IMPORTING
        r_salv_table = go_alv
      CHANGING
        t_table = gt_output ).
    CATCH cx_salv_msg INTO gx_salv_msg.
      MESSAGE 'error' TYPE 'E'.
  ENDTRY.

  go_alv->display( ).
