如何动态创建内部表的名称

使用一张桌子。每行代表您描述的一个ITAB。根据表的索引而不是某个名称对表进行寻址。

TYPES table_type TYPE STANDARD TABLE OF bapiacgl09 WITH EMPTY KEY.
TYPES collection_type TYPE STANDARD TABLE OF table_type WITH EMPTY KEY.

DATA all_results TYPE collection_type.

" collect the results
DO 100 TIMES.
  DATA(single_result) = " call bapi
  INSERT single_result INTO TABLE all_results.
ENDDO.

" access a specific result by index
DATA(forty_second_result) = all_results[ 42 ].

" iterate all results
LOOP AT all_results INTO single_result.
ENDLOOP.

TYPES : BEGIN OF ty_bapiarglist,
          " arguments passed to the BAPI
          accountgl TYPE STANDARD TABLE OF bapiacgl01 WITH EMPTY KEY,
          " ...
          " arguments returned by the BAPI
          return    TYPE STANDARD TABLE OF bapiret2 WITH EMPTY KEY,
          " ...
        END OF ty_bapiarglist.

DATA: bapiarglist  TYPE ty_bapiarglist,
      bapiarglists TYPE TABLE OF ty_bapiarglist.

  APPEND bapiarglist TO bapiarglists.
