copy from internal table to a structure ?

Hello friends,

Is it possible in ABAP to copy the contents of internal table ( of lets say Type XX ) to a structure ( Lets Say YY) where as structure XX and structure YY have some common fields.

Also if I have a structure lets saay YY, and i filled the fields of strucutr inside the loop, and loops runs 10 times do I have 10 entries in the structure, or it overwrite, as I am not doing append or so ??

Loop at .......

YY-a = 1.

YY-b = 2. etc..

EndLoop

Thanks for your input..
