Hi,

Use of these statements will not create a performance issue.

The statement REFRESH BDCTAB works for all internal tables like CLEAR BDCTAB[]. If an internal table BDCTAB has a header line, then the table body and not the header line is initialized. If the internal table BDCTAB has no header line, REFRESH BDCTAB acts like CLEAR itab.

yes, of course I can image ways to cause performance problems by execution of these commands.

But the commands are as explained by themself o.k.

But do the refresh before you use the table in a FOR ALl ENTRIES and you will run into trouble.
