Hi,

No there is no difference.

Since you are using clear with [] this will clear the rows of the ITAB.

Also REFRESH does the same it will clear the itab but keeps the headerline data as it is.

One more thing is REFRESH will clear the memory also and will keep only memory required for number of rows that are mentioned in INITIAL SIZE.

I am sure you are confused with the answers given to your questions but best thing is to write a small program and finding it out. Its some times sad to see pople giving wrong answers.

Regards,

sesh

Hello,

Clear delete the data from workarea or the table header line.

refresh deletes all the entries from the table.

Hi,

clear will clear the header line only.

clear[] will clear the body of the internal table only.

refresh will clear the body of the internal table and header line of that internal table.

aye there IS a difference!

Clear deletes the contents of you workarea, or if you have a itab with headerline, it deletes the contents of the headerline.

Refresh deletes the contents of you itab, tho i´m not a 100% sure but i think the headerline data stays.

Hi Selva,

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.

regards,

Sree

Clear is for header of internal table - i mean it clears only header line of internal table

you can use to variables and internal table

Refresh - clears the body of the internal table and you should not use to variables

Reward Points if it is helpful

Thanks

Both clear the body of the int table .

If for example itab is an internal table with header line.

Now if u write clear itab it will clear the header.

But if u write clear itab[] it will clear the contents but not the header.Same thing happens if u use refresh itab.

Either u can use clear itab[] or refresh itab.both are same.
