Hi Mahesh,

DEFINITION

Dynamic internal table is internal table that we create on the fly with flexible column numbers.

For sample code, please look at this code tutorial. Hopefully it can help you

SAMPLE CODE

pls go through this program.

report z_dynamic.

type-pools : abap.

field-symbols: <dyn_table> type standard table,

<dyn_wa>,

<dyn_field>.

data: dy_table type ref to data,

dy_line type ref to data,

xfc type lvc_s_fcat,

ifc type lvc_t_fcat.

selection-screen begin of block b1 with frame.

parameters: p_table(30) type c default 'T001'.

selection-screen end of block b1.

start-of-selection.

perform get_structure.

perform create_dynamic_itab.

perform get_data.

perform write_out.

form create_dynamic_itab.

Create dynamic internal table and assign to FS

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = ifc

importing

ep_table = dy_table.

assign dy_table->* to <dyn_table>.

Create dynamic work area and assign to FS

create data dy_line like line of <dyn_table>.

assign dy_line->* to <dyn_wa>.

endform.
