本文介绍如何在 ABAP 中通过 cl_alv_table_create 类创建动态表格，并演示了构建字段目录的过程。此外，还展示了如何生成具有相同结构的新行及对其进行测试的方法。

1、使用cl_alv_table_create=>create_dynamic_table

REPORT zmaschl_create_data_dynamic .

TYPE-POOLS: slis.

DATA: it_fcat TYPE slis_t_fieldcat_alv,
is_fcat LIKE LINE OF it_fcat.
DATA: it_fieldcat TYPE lvc_t_fcat,
is_fieldcat LIKE LINE OF it_fieldcat.
DATA: new_table TYPE REF TO data.
DATA: new_line TYPE REF TO data.
FIELD-SYMBOLS: <l_table> TYPE ANY TABLE,
<l_line> TYPE ANY,
<l_field> TYPE ANY.

* Build fieldcat
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
i_structure_name = 'SYST'
CHANGING
ct_fieldcat = it_fcat[].
LOOP AT it_fcat INTO is_fcat WHERE NOT reptext_ddic IS initial.
MOVE-CORRESPONDING is_fcat TO is_fieldcat.
is_fieldcat-fieldname = is_fcat-fieldname.
is_fieldcat-ref_field = is_fcat-fieldname.
is_fieldcat-ref_table = is_fcat-ref_tabname.
APPEND is_fieldcat TO it_fieldcat.
ENDLOOP.

* Create a new Table
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = it_fieldcat
IMPORTING
ep_table = new_table.

* Create a new Line with the same structure of the table.
ASSIGN new_table->* TO <l_table>.
CREATE DATA new_line LIKE LINE OF <l_table>.
ASSIGN new_line->* TO <l_line>.

* Test it...
DO 30 TIMES.
ASSIGN COMPONENT 'SUBRC' OF STRUCTURE <l_line> TO <l_field>.
<l_field> = sy-index.
INSERT <l_line> INTO TABLE <l_table>.
ENDDO.

LOOP AT <l_table> ASSIGNING <l_line>.
ASSIGN COMPONENT 'SUBRC' OF STRUCTURE <l_line> TO <l_field>.
WRITE <l_field>.
ENDLOOP.

2、使用动态创建临时程序 generate subroutine pool code name prog
message msg
line lin
word wrd
offset off.并调。
