1736 Views

Hi ABAP expert


Is the point below a good summary.


Variables -

CLEAR -> delete variable contents - no usage for internal table


Internal Tables -

REFRESH -> delete internal table contents - but do not release the memory spaced occupied previously by the internal table

FREE -> delete internal table contents - and release completely the memory spaced occupied.

Conclusion -

Do you confirm the points below :

1. It's better to use FREE than REFRESH as you want to delete the internal table contents.

2. CLEAR on internal table will only delete the header line contents.


Cheers
