Hello, there are some nice examples in SAP which use this function module, so you might want to check them out ( where used etc. )
In essence, this is a call in one
of my ABAPs
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 and not confuse you,
Cheers.
