LOOP AT itab .
DELETE itab1 WHERE belnr = itab-belnr.
there are 20 lakh records in itab as well as itab1. The execution of this loop is taking a lot of time. Can anyone please suggest an efficient and fastest way to acheive the above requirement. Also i have to delete around 19 lakh entires from itab1 and i cannot filter the data using select queires.
I have tried the below logic too but even that is taking a lot time.
loop at itab1.
read table itab with key belnr = itab1-belnr
binary search transporting no fields.
if sy-subrc <> 0.
append itab1 to itab2.
kindly suggest an efficient logic.
