Read and modify of a internal table in loop-Performance


Hi Experts,

I am working on performance tuning of a report and have come across following situation:

loop at itab

Read table ITAB2 with key field 1 = itab-field1

, field 2 = itab-field2

field 3 = itab-field3

field4 = itab-field4

field5 = itab-field5

if sy-subrc <> 0.

append itab to itab2


modify ITAB2 from itab index lv_index


this code takes couple of minutes to execute , i wanted to using sorting on ITAB2 with 5 fields in where clause and use binary search but the problem is

sorting will get destroyed by the records gets modified.

I tried sorting in loop itself but it will be a performance issues too.

Can some please advice if how can i use a binary search here ?
