Write this code. Hope it helps

PARAMETERS : num TYPE i.

DATA : gt_dyn_table TYPE REF TO data,

gw_line TYPE REF TO data,

gw_line1 TYPE REF TO data.

FIELD-SYMBOLS: <gfs_dyn_table> TYPE ANY TABLE.

DATA : gw_dyn_fcat TYPE lvc_s_fcat,

gv_pos(4) TYPE n,

gt_dyn_fcat TYPE lvc_t_fcat.

DATA : str TYPE string.

DO num TIMES.

gv_pos = gv_pos + 1.

CLEAR str.

CONCATENATE 'FIELD' gv_pos INTO str .

gw_dyn_fcat-fieldname = str.

gw_dyn_fcat-outputlen = 1.

gw_dyn_fcat-col_pos = gv_pos.

APPEND gw_dyn_fcat TO gt_dyn_fcat.

CLEAR gw_dyn_fcat.

ENDDO.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_dyn_fcat

IMPORTING

ep_table = gt_dyn_table

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

IF sy-subrc EQ 0.

ASSIGN gt_dyn_table->* TO <gfs_dyn_table>.

ENDIF.
