Hi Srinivas
·        Screen number
A four-digit number, unique within the ABAP program, that identifies the screen within the program. If your program contains selection screens, remember that the screen numbers of selection screens and Screen Painter screens both use the same namespace. For example, if you have a program with a standard selection screen, you may not create any further screens with the number 1000. Lists, on the other hand, have their own namespace.
·        Screen type
- A normal screen occupies a whole GUI window.
- Modal dialog boxes only cover a part of a GUI window. Their interface elements are also arranged differently. - Selection screens are generated automatically from the definition in the ABAP program. They cannot be generated using the Screen Painter.
- A subscreen is a screen that you can display in a subscreen area on a different screen in the same program.
·        Next screen
Statically-defined screen number, specifying the next screen in the sequence. By entering zero or leaving the field blank, you define the current screen as the last in the chain. If the next screen is the same as the current screen, the screen will keep on calling itself. You can override the statically-defined next screen in the ABAP program.
·        Cursor position
Static definition of the screen element on which the cursor is positioned when the screen is displayed. By default, the cursor appears on the first input field. You can overwrite the static cursor position dynamically in your ABAP program.
·        Screen group
Four-character ID, placed in the system field sy-dyngr while the screen is being processed. This allows you to assign several screens to a common screen group. You can use this, for example, to modify all of the screens in the group in a uniform way. Screen groups are stored in table TFAWT.
·        Holding data
If the user calls the screen more than once during a terminal session, he or she can retain changed data as default values by choosing System
Layout Editor
We use layout editor to place screen element in screen layout. There are two modes in editing layout: Graphical and alphanumeric. Both modes offer the same functions but use different interfaces. In graphical mode, you use a drag and drop interface similar to a drawing tool. In alphanumeric mode, you use your keyboard and menus. It is easier to work in graphical mode, to toggle beetween this mode, in SE51 go to: Utilities->Settings: in screen painter tabs check graphical layout editor.
Layout editor contains these tools:
i. Element pallete
On left screen you will find list of element (textbox, label, checkbox) you can use. Drag and drog element to put it on screen.
ii. Name & Text
Aftef put element on screen, write its name and text (in textbox, text will set default value).
iii. Attributes Window
Double click the element to display its attributes, or select it then click :Goto->Secondary window->attributes. For example, in textbox element, we can set its length, read only mode, in this window.
iv. Dictionary/program field.
If we want to create a field refer to field in data dictionay or field already declared in program, use this menu to create text field with the same type compared to its referral.
