Answer / sirisha

CLEAR and FREE are similar. They free the data from work
area. an internal table with work area, CLEAR itab clears
work area. Where as clear itab[] removes contents of the
table. It will not free the memory.

But with the FREE, it not only clears data from the internal
table, but also the memory.

REFRESH always deletes the data from the internal table.
Work area data will not be deleted. It frees the memory
alloted to the internal table.
REFRESH itab is similar to clear itab[].
