Hi Experts,

Please some body let me know how to use ALV Function

REUSE_ALV_FIELDCATALOG_MERGE .While we use fieldcat to provide

manual data so how to use above function module to extract Dataelement

features.

thanks

We use this FM to get the internal table columns in the list. You need to pass the program name, the structure of the internal table to the function module and get the field catalog structure.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = v_repid

i_internal_tabname = 'ITAB'

I_STRUCTURE_NAME =
I_CLIENT_NEVER_DISPLAY = 'X'

i_inclname = v_repid

i_bypassing_buffer = 'X'

i_buffer_active = ' '

CHANGING

ct_fieldcat = i_fieldcat

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Regards,

Navneet
