Hi,

SORT the table before you use BINARY SEARCH In READ.

SORT ITAB BY ....

READ TABLE ITAB .......... BINARY SEARCH.

This is needed if your table is of type STANDARD, not required if it is SORTED and cannot use if it is HASHED.

Sesh

Hi Rahul,

You need to sort the internal table before the loop when you are using BINARY SEARCH

You have to sort those fields which u r using in where condition for the READ statement

Its depends on Wat data ur fetching into internal table.

If its item data it happens like that.

So before using binary search sort it and delete adjacent duplicates.

Hi,

1) sort the table outside the loop which u r reading.

2) sort the table with keys by which u r reading the table in the same sequence.

SORT: p_it_vbkd BY vbeln posnr,

p_it_t001 BY bukrs,

p_it_vbkd1 BY vbeln posnr,

p_it_vbrp BY vbeln.

LOOP AT p_it_out INTO lw_out.

READ TABLE p_it_vbrp

INTO lw_vbrp

WITH KEY vbeln = lw_out-vbeln1

BINARY SEARCH.

If aubel is not intial

IF NOT lw_vbrp-aubel IS INITIAL.

Get exchange rate from it_vbkd for a line item

READ TABLE p_it_vbkd

INTO lw_vbkd

WITH KEY vbeln = lw_vbrp-aubel

posnr = lw_vbrp-posnr

BINARY SEARCH.
