BADI for operation long text.

Hi ALL,

I have a requirement to track the changes done in operation long text in the TCODE IW32.

The operation long text is a text element. I need to pick up the new as well as old value.

Do we have any BADI which will store the values.

My requirement is to implement a BADI with these changes.

Thanks for any response in advance.

Thanks and regards,

Krishna.
