which table has (dynpro) screen fields attributes?

Hi Experts,

Is there any FM to find out the screen elements (dynpro not webdynpro) and their attributes ?

Which table has the information about screen elements and their attributes?

My requirement is to find out all the elements in a screen when i provide the program name and the screen number. I also need to know the element type like 'Text Label' or 'Push Button'.

Thanks in advance.
