Duplicate dynamic table in - cl_alv_table_create=>create_dynamic_table

Former Member — Fri, 16 Apr 2010 08:44:39 GMT

Hi Gurus,

I have done the following code, but it is not treating <alv_table> and <alv_table_new> as different tables.

How can I create a duplicate table of <alv_table> in the below context ??

DATA : ldtab TYPE REF TO data,

ldtab_NEW TYPE REF TO data.

FIELD-SYMBOLS: <alv_table> TYPE table,

<alv_table_NEW> TYPE table.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_fcat

IMPORTING

ep_table = ldtab.

IF sy-subrc = 0.

ldtab_new = ldtab.

ASSIGN ldtab->* TO <alv_table>.

ASSIGN ldtab_new->* TO <alv_table_new>.

ENDIF.

Regards,

Sandip.

hi,

Both field symbols i.e. <alv_table> and <alv_table_new> are pointing to same memory area because of the statements

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_fcat

IMPORTING

ep_table = ldtab.

IF sy-subrc = 0.

ldtab_new = ldtab. <----

do not perform this step

ASSIGN ldtab->* TO <alv_table>.

ASSIGN ldtab_new->* TO <alv_table_new>.

endif.

instead write -

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_fcat

IMPORTING

ep_table = ldtab.

IF sy-subrc = 0.

ASSIGN ldtab->* TO <alv_table>.

endif.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_fcat

IMPORTING

ep_table = ldtab_new.

IF sy-subrc = 0.

ASSIGN ldtab_new->* TO <alv_table_new>.

endif.

try the above mentioned code.

I hope this will resolve your issue.

Regards,

Sambaran Ray

Hi Sandip,

cl_alv_table_create=>create_dynamic_table is no good, use run time type services instead, search for CL_ABAP_TYPEDESCR.

Anyway,

ASSIGN ldtab->* TO <alv_table>.
CREATE DATA ldtab_new like  <alv_table>.
ASSIGN ldtab_new->* TO <alv_table_new>.

creates a second internal table like the first one - not pointing to the same memory area.

Clemens

You can refer to these two articles for two different ways of creating dynamic internal table-

Hope it helps.

Hi Sandip,

Have a look at this following Wiki . It clearly explains the way you can create Multiple dynamic Internal Tables.

http://wiki.sdn.sap.com/wiki/display/Snippets/CreateMultipleDynamic+Tables

Hope this will help.

Thanks,

Samantak.

Hello Sandip,

SDN is full of material on how to create dynamic internal table but my only advice is to not to use static method from class cl_alv_table_create=>create_dynamic_table. Instead you can refer to ABAP RTTS (Run Time Type Services) for creating dynamic internal tables.

Thanks,

Augustin.
