For this you will need a nested internal table. such that each column of the internal table should be declared as another internal table.
Try something like this :
" Lets say that the type of table that will be returned by the function BOM is ty_ret_tab, then declare as follows
types begin of ty_tab,
c1 type table of ty_ret_tab,
c2 type table of ty_ret_tab,
end of ty_tab.
data gt_tab type standard table of ty_tab,
        gwa_tab like ty_tab.
Now the question is how many columns should you declare ? Because you said that in a loop you intend to call a function which will return a internal table and this internal table you need to store in a column of another internal table. And if this is not fixed, you would need to do some dynamic programming to achieve this.
But if we assume that there are fixed number of columns and fixed number of loops, then within the loop, you wiill have to simply move the data from the returned table to each of the columns. Then append the work area outside the loop.
data field(30) type c.
data c_tabix(10) type c.
field-symbols <fs> type ret_tab.  " this should be
Loop at itab.
call function BOM...
exporting...
importing.....
tables  ret_itab.
c_tabix = sy-tabix.
concatenate 'C' c_tabix into field.
condense field.
assign component  (field) of structure gwa_tab to <fs>.
<fs> = ret_tab.   " Pass data to each column
endloop.
append gwa_tab to gt_tab.  " Now a single record with all columns containing an internal table is built.
Hope this pseudo code helps.
