The NO-DISPLAY is used for not displaying the parameter/select-option on the selection screen.
When you execute the program stand alone, that time the use of not displayed parameter is only like a normal work area..
But we use them when we call this program from another program using SUBMIT REPORT statment. This time we can pass a value to this parameter..
So, see if u want to build an application, such that when u execute it stand alone, it should give one result and when you call this from another program, it should give some other result..
This can be acheived by use of NO-DISPLAY parameter.
By using NO-DISPLAY for select-options is kind of parameter, but apart from this u can enter multiple single values into this field. And you cannot enter ranges of values by using NO-DISPLAY.
To avoid using ranges and able to enter multiple single values.

The LOW and HIGH fields of a selection option are displayed in a length up to 18 bytes long (scrollable up to 45 bytes). If you define a length longer than 45, fields are truncated on the selection screen after the 45th character. This affects the first line of the SELECT-OPTIONS table. You can, however, pass longer selection options to a report if they are specified with the addition NO-DISPLAY and thus do not appear on the selection screen. Without NO-DISPLAY , the fields are then truncated whenever the selection screen is processed in the background (SUBMIT without VIA SELECTION-SCREEN ).
... NO-DISPLAY
Effect
Does not display the selection on the selection screen. Creates the internal table sel as with 'normal' selection options and you can then transfer the selection option with SUBMIT .
These selection options represent a part of the interface which the user does not see on the selection screen. You can set the values either internally (through the routine INIT in SAPDBldb or INITIALIZATION in the report) or with SUBMIT . These selection options are also stored for variants.
Sometimes, (e.g. when the user has entered particular values for other selection options or parameters ), you may want to display these undisplayed selection options on the screen so that the user can enter values. You can do this in the routine PAI of the database program SAPDBldb (for database-specific selection options) or under AT SELECTION SCREEN (for report-specific selection options) by calling a function module (see CALL FUNCTION ) or your own screen (CALL SCREEN .
