Hi,

Check this demo program:

BCALV_FIELDCAT_TEST

(This report allows to modify the fieldcatalog of a corresponding

output table and to view the effects of your changes directly.)

Hi Anju,

This will create columns dynamically,check it out:

DATA: dt_outtab TYPE REF TO data.

FIELD-SYMBOLS: <outtab> TYPE STANDARD TABLE.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING i_structure_name = 'ZSOME_EXISTING_STRUCTURE'

i_client_never_display = 'X'

CHANGING ct_fieldcat = t_fcat.

s_fcat-fieldname = 'NEW_FIELD'.

• ...supply all other fieldcat attributes

APPEND s_fcat TO t_fcat.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING it_fieldcatalog = t_fcat

IMPORTING ep_table = dt_outtab.

ASSIGN dt_outtab->* TO <outtab>.

*... create your ALV

CALL METHOD alv->set_table_for_first_display

CHANGING it_outtab = <outtab>

it_fieldcatalog = t_fcat.
