To write a Generic Programming to accept any internal table

Former Member — Mon, 14 May 2007 09:24:01 GMT

Hi Gurus,

<i>By Generic Programming</i>

May I know how to write a form WRITE_TABLE which accepts any internal table and also to write the contents of the internal table to the ABAP list, line

by line and field by field?

Thanks,

Raja

Hi,

try

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.
