Hi,

It is used for Hierarchical sequential list output

<b>Functionality</b>

This module outputs two internal tables as a formated hierarchical-sequential list.

<b>Principle:</b>

Pass an internal table containing the set of header information to be output.

Pass an internal table containing the set of item information to be output.

Pass a structure containing the general list layout details

Pass a field catalog in the form of an internal table. The field catalog describes the fields to be output in the list.

Regards,

Padmam.

The function module REUSE_ALV_HIERSEQ_LIST_DISPLAY is used for ALV Hierarchical sequential list output.

An Example Prg..

CALL FUNCTION 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'

EXPORTING

i_interface_check = 'I'

i_callback_program = gv_repid

i_callback_pf_status_set = 'STATUS_DATA'

i_callback_user_command = 'COMMAND_DATA'

is_layout = gs_layout

it_fieldcat = gt_fieldcat

i_default = ' '

i_save = 'A'

i_tabname_header = v_headers_itable

i_tabname_item = v_items_itable

i_structure_name_header = v_headers_table

i_structure_name_item = v_items_table

is_keyinfo = gs_keyinfo

i_bypassing_buffer = 'X'

TABLES

t_outtab_header = i_headers

t_outtab_item = i_result

t_outtab_item = i_report

EXCEPTIONS

program_error = 1

OTHERS = 2.

The field cat creation worked like this :

FORM fieldcat.

DATA: ls_fieldcat TYPE slis_fieldcat_alv.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_internal_tabname = v_items_itable

i_structure_name = v_items_table

CHANGING

ct_fieldcat = gt_fieldcat.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_internal_tabname = v_headers_itable

i_structure_name = v_headers_table

CHANGING

ct_fieldcat = gt_fieldcat.

ENDFORM.

and of course you need to tell the thing what is key and item

gs_keyinfo-header01 = 'PA'.

gs_keyinfo-item01 = 'PA'.

gs_keyinfo-item02 = 'SAPDOC'.

PERFORM fieldcat.

I hope this helps you
