comparing to working areas in order to find the different.

hi

i am selecting the current row of an employee from infotype 1 to wa_1 and his previous row to wa_2.

is the an easy way to compare between the two wa ( wa_1 to wa_2 ) insted of comparing each column in wa_1 to the same column in wa_2 ?

i need to find the different between the two row .

thanks
