[Former Member]

1.I have 3 columns in ITAB say col1,col2,col3

SORT itab BY col1 col2 col3.

Reab TABLE itab WITH KEY col1 = ... col3 = ... col2=.... WITH BINARY SEARCH.

Will it work? If not why....

2.What are the things we need to check before a READ statement with binary search?

Hi Siva,

The prerquisites is that the standard table must be sorted in ascending order by the specified search key.The binary search works faster than the linear search.

You need to check whether the <b>internal table is sorted</b> according to requirements before doing binary search

READ TABLE ITAB WITH KEY FIELD1 = ITAB2-FIELD2 BINARY SEARCH.
