How about this:


DATA:
  gr_structdescr  TYPE REF TO cl_abap_structdescr,
  gr_tabldesct    TYPE REF TO cl_abap_tabledescr,
  gr_dref         TYPE REF TO data.

FIELD-SYMBOLS:
  <gt_table>  TYPE STANDARD TABLE.

gr_structdescr ?= cl_abap_structdescr=>describe_by_name( <f_table ).
gr_tabledescr ?= cl_abap_tabledescr=>create( gr_structdest ).

CREATE DATA gr_dref TYPE HANDLE gr_tabledescr.
ASSIGN gr_dref->* TO <gt_table>.

* now field-symbol <GT_TABLE> points to an internal standard
* table with the same structure as the DDIC table specified in
* <F_TABLE>

All the columns are not getting copied, into the output field symbol.

Any better solution to over come this.

Please quote the code that is executed to fill the internal table! I don´t think this issues reason is the dynamically creation of the internal table...

Hi,

FIELD-SYMBOLS:

<gt_table> TYPE STANDARD TABLE.

gr_structdescr ?= cl_abap_structdescr=>describe_by_name( <f_table ).

gr_tabledescr ?= cl_abap_tabledescr=>create( gr_structdest ).

CREATE DATA gr_dref TYPE HANDLE gr_tabledescr.

ASSIGN gr_dref-> TO <gt_table>.*

Reply back..

@S BHARANIDARAN:

ATTENTION:

the code quoted by you only creates and initializes the internal table, it does not fill the internal table!
