SCREEN is a structure only.

But when you create a screen or selection-screen; the program which controls your screen or selection-screen creates an internal table with header line of type SCREEN.

So in your program SCREEN is an internal table, you can always loop it.

To understand it better, write some parameters and select-options in a report program; in debugging mode see the details of SCREEN table.

SCREEN is an SAP system 'table' that we manipulate within ABAP's to control the fields on the screen, whether they are active, input allowed etc.

The processing done as part of PBO.

The coding usually goes inside an OUTPUT Module, you can debug through processing.

LOOP AT SCREEN.

Coding here e.g. Hide a group of fields for a country code.

IF SCREEN-GROUP1 = gv-country.

SCREEN-ACTIVE = 0.

ENDIF.

MODIFY SCREEN. "We often forget this!

ENDLOOP.

k Surya is right .. SCREEN is a stucture that has some predefined fields .

FYI :

Plz create some fields , textelements , select-options on the screen used in ur program.

In the PBO event ( for module pool programs ) or at INITIALIZATION ( for normal report programs ) event,

LOOP at screen.

"this would enable u to see all the elements u've created on the screen.

ENDLOOP.
