How to code this - Please advise

Question

Dear friends,
     Please advise as how to code the below scenario in order to obtain the best performance.
I've an internal table IT_BSAD.Now I've to check if in the combination of bukrs,augbl,auggj,kostl,prctr,gsber,aufnr, if there is a single record in IT_BSAD, then it should be appended to IT_BSAD1 & if there are multiple records, then those should be appended to IT_BSAD2. In any case IT_BSAD1 & IT_BSAD2 should not contain duplicate records & records in IT_BSAD = records in IT_BSAD1 + Records in IT_BSAD2. I coded it somehow but it hangs in case of million of records. Please advise me the best way of doing it.
I'll appreciate any help in this regard.
Thanks:
Gaurav

Answer 1

prepare a sorted table with key bukrs,augbl,auggj,kostl,prctr,gsber,aufnr
loop it_basd assigning <fs_basd> .
at new sufnr.
lv_index = 0.
endat.
" move the fields to it_basd1 work area
"append it_basd1
lv_index = lv_index + 1.
if lv_index > 1.
if lv_index = 2.
read it_basd1 into iwa_basd2 with key  bukrs,augbl,auggj,kostl,prctr,gsber,aufnr.
append iwa_bsad2 into it_bsad2.
delete from  it_basd1 where  bukrs,augbl,auggj,kostl,prctr,gsber,aufnr.
endif.
" move the fields of <fs_basd> to it_basd2 work area
append iwa_bsad2 into it_bsad2.
endif.
endloop.
hope this will help
