itab created dynamically

Former Member — Tue, 24 Jul 2007 07:54:46 GMT

Hi. Is there some possibility to define table whilst program flow?


DATA: BEGIN OF some_pattern,
        ...
      END OF some_pattern.

PARAMETERS: num LIKE i.
DATA: itab LIKE some_pattern OCCURS num.

Greetings. P.

Hi,

Check the following code for creation of dynamic internal table.

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,

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.

Reward if helpful.
