Dynamic Internal Table declaration.

former_member190178 — Mon, 12 Jan 2009 05:54:46 GMT

Hi Experts,

I have Table Name on the selection screen. Inside program I would like to create the Internal table based on the users input example if user gives MARA then internally Internal should be declared of MARA type.

How can we achieve this ? Please reply.

Here are several examples how you can process the dynamic table afterwords.

now you have a line of the internal table

FIELD-SYMBOLS: <fs_dyn_table> LIKE LINE OF dyn_table.

this can be used for any field

FIELD-SYMBOLS: <fs_component> TYPE ANY.

example read

READ TABLE dyn_table ASSIGNING <fs_dyn_table>

INDEX 1.

example loop

LOOP AT dyn_table ASSIGNING <fs_dyn_table>.

place your coding here

ENDLOOP.

once you have a line you can display its elements

DO.

ASSIGN COMPONENT sy-index OF

STRUCTURE <fs_dyn_table> TO <fs_component>.

IF sy-subrc 0. EXIT. ENDIF.

WRITE / <fs_component>.

ENDDO.

if you want to display by name

ASSIGN COMPONENT 'COMPONENT_NAME' OF STRUCTURE <fs_dyn_table>

TO <fs_component>.

IF sy-subrc EQ 0.

WRITE: / 'Specific component ' , <fs_component>.

ENDIF.

Hello

I advise against using method cl_alv_table_create=>create_dynamic_table. Instead I recommend to use either RTTI or data objects (if available in your SAP release) to create these runtime objects.


DATA: ldo_data   TYPE REF TO data,
          ld_tabnam TYPE tabname.

FIELD-SYMBOLS:
  <lt_itab>    TYPE TABLE.


ld_tabnam = 'MARA'.
CREATE DATA ldo_data TYPE STANDARD TABLE OF ( ld_tabnam ).
ASSIGN ldo_data->* TO <lt_itab>.

SELECT * FROM (ld_tabnam) INTO TABLE <lt_itab>.

Regards

Uwe
