Previous value of sy-ucomm

Hi everyone,

Suppose I have 2 buttons in  a screen and i have pressed both buttons one after another.

Now, SY-UCOMM will store the current value as the fcode of second button which i pressed in the last.

My question is,

is there any way to retrieve the previous value of sy-ucomm i.e the fcode of first button here.

Thanks in advance.

Regards,

Roshan.
