如何使用cl_salv_bs_runtime_info

Question

我正在尝试检索由程序 RFKSLD00 生成的 ALV table，但我无法使 cl_salv_bs_runtime_info 工作。这是我拥有的：

我不得不在 SET 方法中指定一个强制性参数结构（我不知道它的值是什么，所以我只输入了 ''）。此外，方法 GET_DATA_REF 不存在，所以我使用 GET_DATA 代替，现在我得到：

"LR_PAY_DATA" is not type compatible with formal parameter "T_DATA".

可能是因为有更新或其他帖子没有这些问题。

我做错了什么？

Answer 1

T_DATA 参数属于 TABLE 类型，您正试图将 REF TO DATA 传递给它。

您需要传递一个 table.

变量

在你的例子中，它可以像这样完成。

TRY.
    ASSIGN lr_pay_data->* TO <lt_pay_data>.
    cl_salv_bs_runtime_info=>get_data(
      IMPORTING t_data = <lt_pay_data> ).
  CATCH cx_salv_bs_sc_runtime_info.
    MESSAGE `Unable to retrieve ALV data` TYPE 'E'.
ENDTRY.

当然，首先你必须在某个时候初始化 lr_pay_data，因为我在你的代码中没有看到它。
