To display the alv using 'REUSE_ALV_HIERSEQ_LIST_DISPLAY' FM
To display the alv in a different manner we have to pass some additional parameters.
For the header as in the output maintain a separate internal table it_final_hdr.
To get the code click on below link :
BEGIN OF t_final_hdr,
vkorg TYPE vbak-vkorg,
vname TYPE tvkot-vtext(tvkot),
kunnr TYPE vbak-kunnr,
kname TYPE kna1-name1,
expand,
END OF t_final_hdr,
i_final_hdr TYPE TABLE OF t_final_hdr.
I_final is the final table.
w_fcat-fieldname = 'VNAME'.
w_fcat-outputlen = '25'.
w_fcat-seltext_m = 'Sales Organisation'(002).
w_fcat-tabname = 'I_FINAL_HDR'.
APPEND w_fcat TO fcat.
CLEAR w_fcat .
w_fcat-fieldname = 'KNAME'.
w_fcat-outputlen = '25'.
w_fcat-seltext_m = ‘BUYER.
w_fcat-tabname = 'I_FINAL_HDR'.
APPEND w_fcat TO fcat.
CLEAR w_fcat .
gs_layout-expand_fieldname = 'EXPAND'.
gs_layout-expand_all = 'X'.
gs_layout-subtotals_text = text-018.
After that built the catalog for the fields for final table.
LOOP AT i_final INTO w_final.
w_final_hdr-kunnr = w_final-kunnr.
w_final_hdr-vkorg = w_final-vkorg.
CLEAR: w_kna1, w_vkorg.
READ TABLE i_kna1 INTO w_kna1 WITH KEY kunnr = w_final-kunnr.
w_final_hdr-kname = w_kna1-name1.
READ TABLE i_vkorg INTO w_vkorg WITH KEY vkorg = w_final-vkorg.
w_final_hdr-vname = w_vkorg-vtext.
APPEND w_final_hdr TO i_final_hdr.
ENDLOOP.
FORM key_info.
gs_key-header01 = 'VKORG'.
gs_key-item01 = 'VKORG'.
gs_key-header02 = 'KUNNR'.
gs_key-item02 = 'KUNNR'.
