why can we use 'loop at screen' to loop the screen structure?

Hi all,

Screen is a structure in ABAP Dictionary, but we also can use 'loop at' statement for the special structure ? How does the system work?

Thanks and Best regards,

Hi Ram,

Screen is a structure, so we need a system table to store the screen elements. Who can tell me the table's name and how does it pass the values to the structure?

Thanks

HI Lu,

There is no datbase table where you'r screen details get updated. This is a run time process, as soon you run your program, structure SCREEN had the screen details. You can create you'r table by looping this structure and appending the table
