Match 2 itab into 1 alv with not identical header.

Question

Hello experts,
I have 2 itab:  it_reguh  with 12 fields, and it_regup with 9 fields.
For all 1 row from it_reguh can be some row correctly in it_regup, and header not identical.
How can i to join them  to 1 alv  with the header of it_reguh and header of it_regup ?
For example:  ALV like this:
IT_REGUH-HEADER.
IT_REGUH-ROW1.
IT_REGUP-HEADER.
IT_REGUP-ROW1.
IT_REGUP-ROW2.
IT_REGUH-HEADER.
IT_REGUH-ROW2.
IT_REGUP-HEADER.
IT_REGUP-ROW1.
IT_REGUP-ROW2.
Thanks for the help,
Avi.

Hi,
Generally this is the relationship between Header(REGUH) and Item(REGUP)
**  Getting the item Data REGUP from header table REGUH
    CLEAR : l_regup_data,wa_with_item.
    REFRESH :l_regup_data.
    SELECT *  FROM regup INTO TABLE l_regup_data
                                  WHERE laufd = reguh_data-laufd
                                  AND   laufi = reguh_data-laufi
                                  AND   xvorl = reguh_data-xvorl
                                  AND   zbukr = reguh_data-zbukr
                                  AND   lifnr = reguh_data-lifnr
                                  AND   vblnr = reguh_data-vblnr.
    IF sy-subrc = 0.
    ENDIF.
so try to create common internal table with Reguh and regup table.
write the below query
Loop at regup.
read table reguh with above key combination.
If sy-subrc = 0.
     "Append reguh and regup contents to final internal table
endif.
ENDloop.
