CLEAR is used to clear variables and structures, work areas, and/or header lines of internal tables.. REFRESH is used to clear the body of an internal table.

Refresh is used to refresh the body contents of the internal table. This is used if in case internal table is not declared with header line.

Clear is used to clear the contents in the work area or header line.

Clear[] is similar to refresh itab - This refresh the contents of the body.

If you have defined an internal table ITAB with header line.

1) CLEAR statement will clear the header line only.

2)If you need to clear the body use CLEAR ITAB[].

3) REFRESH ITAB will work the same as CLEAR ITAB[].

Hi Diana,

Refresh itab.

The internal table itab is reset to its initial state, i.e. all table entries are deleted.

When we use refresh, the header entry of a table with a header line remains unchanged. It can be reset to its initial value using CLEAR.

clear itab --> clears the value in the header line .

clear itab[] --> works same as Refresh.
