[former_member391265]

Hi all, I have a statement below - This is being asked in 1 of the interview. please clear my doubt.. both codes will bring same result... itab1, itab2 &itab3 declare with headerline. LOOP AT ltab1 WHERE  ABC  = ltab2-ABC                     AND XYZ = ltab2-XYZ.                        MOVE-CORRESPONDING ltab1 TO itab2.       MOVE itab2 TO itab3.       APPEND itab3. endllop. CAN I WRITE/OPTIMIZE above code itab1, itab2 &itab3. wa1, wa2 & wa3. LOOP AT ltab1 into wa1 WHERE  ABC  = wa2-ABC                     AND XYZ = wa2-XYZ.                        MOVE-CORRESPONDING wa1 TO wa2.       APPEND wa2 TO itab3 . endllop. is there any difference in above 2 statements..

check this

What are the benefits of using work areas with tables, as opposed to header lines?

[former_member391265]

Thats ok.. but my both codes will result same output or different output?
