如何仅在 Table 处循环引用数据

Question

我正在使用函数模块 RSAQ_QUERY_CALL，返回 table:

DATA: gr_data TYPE REF TO data.

CALL FUNCTION 'RSAQ_QUERY_CALL'
     EXPORTING
       query          = 'ZXXXXXXXX'
       usergroup      = 'XXX'
       VARIANT        = 'TEST'
       SKIP_SELSCREEN = 'X'
       DATA_TO_MEMORY = 'X'
     IMPORTING
       ref_to_ldata   = gr_data
     EXCEPTIONS
       OTHERS         = 11.

现在我该如何循环 table？

我尝试了什么：

分配给字段符号
传递字段符号而不是 dref

两者均无效。

Answer 1

我找到了解决办法（问了前辈..）

FIELD-SYMBOLS: <gt_data> type table,
               <row>     type any.

ASSIGN gr_data->* to <gt_data>.

LOOP AT <gt_data> ASSIGNING <row>.

  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE <row> TO <field>.
    IF sy-subrc <> 0.
      EXIT. " last field of row
    ENDIF.

    WRITE : / 'Field', sy-index, ':', <field>.

  ENDDO.
    
ENDLOOP.

Answer 2

参考这段代码：

    FIELD-SYMBOLS: <gt_data> type table,
                   <fs_value> type any.
    ASSIGN gref_data->* to <gt_data>.
    LOOP AT <gt_data> ASSIGNING <fs_value>.
         write:<fs_value>.                 "Here you will get row by row
    ENDLOOP.
