Answer 1

if its a ztable then better to keep a counter field for your requirement.
else.
parameter : count type i. "this holds number of required data.
select * from TT_XYZ into table gt_itab.
loop at gt_itab into gs_itab.
at end of post_no.
   count = count - 1.
endat.
if count = 0.
  exit.
endif.
append gs_itab to gt_itab2.
clear gs_itab.
endloop.
now gt_itab2 holds required entries for you.
