Read statement failure in sap abap

Internal Table name : itab_final.

work area   name : wa_final

itab_final having 4 records as follows.

S.NO      UID    UNAME  

1            A1       AUDI

2            B1       BMW

3            R1       RENAULT

4            H1       HONDA

I have one variable CID holding  value R1.


In my program I have a READ statement like

READ TABLE itab_final  INTO wa_final WITH KEY uid = cid BINARY SEARCH.

we have R1 in itab_final but still will  get SY-SUBRC as 8 (READ statement failure) when we execute the above READ statement.


Solution 1 :

READ TABLE itab_final  INTO wa_final WITH KEY uid = cid .

Solution 2:

SORT itab_final by uid.

READ TABLE itab_final  INTO wa_final WITH KEY uid = cid BINARY SEARCH.

Sort the internal table based on the field which is used in READ statement as WITH KEY .


Conclusion : Both Solution 1 and Solution 2 will work fine. But when compare to Solution 1 , Solution 2 is better in performance wise.
