Loop performance

sudha_naik — Mon, 24 Sep 2007 06:38:44 GMT

Hello all

I have a loop which is coded as below ..

LOOP AT ij_cawn

WHERE atinn = j_3apghd-j_3abzd1.

EXIT.

ENDLOOP.

When analysis was done using ST12, this was shown to take huge time. I would like to modify this code as

Read tavel ij_cawn with key atinn = j_3apghd-j_3abzd1.

Binary search is not possible as the table is not sorted . Also I cannot sort it due to some other logic.

Could you please give me your valuable sggestions in thsi ..

Regards

Sudha

hI,

YOUR LOGIC IS RIGHT,

USE READ STATEMENT AND THEN WRITE IF SY-SUBRC = 0.

PERFORM STEPS.

ENDIF.

i_temp[] = ij_cawn[].

sort i_temp by atinn.

Read table i_temp with key atinn = j_3apghd-j_3abzd1 BINARY SEARCH.
