Get the Common from Two Internal Tables with same structure

Hi ,

I need to get the Common data from Two Internal Tables with same structure with using the looping method.

For e.g.

I have two internal table say ITAB1 and ITAB2.

ITAB1 has values A,B,C,D,E,F

ITAB2 has values A,H,B,Y,O

Output at runtime should be : A,B
