Hi Srinivas,
read table fp_it_temp into l_wa_temp with key kunwe eq <l_fs_final_today>-kunwe
matnr eq <l_fs_final_today>-matnr
vbeln ne <l_fs_final_today>-vbeln binary search.
if sy-subrc = 0.
lv_index = sy-tabix.
endif.
loop at fp_it_temp into l_wa_temp from lv_index.
if l_fs_final_today ne l_wa_temp-kunwe. "Add if you need other conditions.
exit.
endif.
"Write your respective coding here
endloop.
