To reset a variable <f> to the appropriate initial value for its type, use the statement

CLEAR <f>.

This statement has different effects for different data types:

Elementary ABAP types

The CLEAR statement sets the value of an elementary variable to the initial value specified for its type (see the table in Predefined ABAP Types), and not to the starting value that you specified in the VALUE addition to the DATA statement.

References

The CLEAR statement resets a reference variable to its initial value, that is, so that it does not point to an object.

Structures

The CLEAR statement resets the individual components of a structure to their respective initial values.

Internal tables

The CLEAR statement deletes the entire contents of an internal table (see also Initializing Internal Tables).

You cannot use the CLEAR statement to reset a constant.

DATA NUMBER TYPE I VALUE '10'.

WRITE NUMBER.

CLEAR NUMBER.

WRITE / NUMBER.

The output appears as follows:

10

0

The CLEAR statement resets the contents of the field NUMBER from 10 to its initial value 0.

Hi,

There is no such command.

One way you can do it like HIDE screen elements.

Use AT SELECTION SCREEN OUTPUT in that modify screen and make elements invisible.

Reward if useful!

i don't think there is any particular syntax for clearing a screen.

u can definitely clear a filed and work area and body of internal tables as told by our friends.

Well,

You cannot actually clear the screen in ABAP.

However, we can create the illusion that the screen is clear.

if we use the statement 'write : /' around 100 times,

the cursor goes 100 rows below.

This gives an impression that the screen is clear.

However a scrollbar is there.
