Creating table column dynamically?

[Former Member]

Hi,

I need to display some information using ALV. But my table's columns are not static. Its column size can be change respect to station. Now, It it possible to add new columns to internal table and show with ALV?

Thanks.

Can'nt we try to fill field catalog based on the logic?

Hi,

I mean that my internal table's column size can be 10 or 15 or 17 or another number respect to user's selection. So, I can not define internal table statically.

As manohar said modify the field catalog and dont forget to call

REFRESH_TABLE_DISPLAY method of cl_gui_alv_grid. (i assume you are using class based ALV)

in such a case you need to define the internal table dynamically

which can be done using

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = it_fieldcat

importing

ep_table = new_table.

search this forum for code sample on using this.

then you need to create dynamic internal table and respective field catalog.

HI,

This is a Example progrma to create a Dinamic Internal table

append ls_alv_cat to i_alv_cat.
endloop.

call method cl_alv_table_create=>create_dynamic_table
exporting it_fieldcatalog = i_alv_cat
importing ep_table = d_ref .
assign d_ref->* to <f_fs>.

loop at <f_fs> assigning <f_fs2>.

endloop.

endloop.

Hope this helps you

Hi,

Take a look at these blogs which deal with dynamic internal tables ....

/people/ravikumar.allampallam/blog/2005/05/31/expand-the-list-of-columns-in-a-report-dynamically

/people/subramanian.venkateswaran2/blog/2004/11/19/dynamic-internal-table

/people/rich.heilman2/blog/2005/07/27/dynamic-internal-tables-and-structures--abap

You will have to create the entire internal table dynamically, once created you cannot add any more fields to the table.

Ravi
