Compare previous value and new value on Campaign Save

Question

Hi All,
I create a campaign. I need some exit ( badi etc.) which is called before saving the campaign and after saving the campaign. My main intention is to compare the previous value and the new value.
Thanks in advance,

Yes, you would have to write code that specifically compared each column. And update that code when the column list changed. Of course, you could always write code that generated your triggers for you based on the column definitions.
On the other hand, I would tend to suggest that if you need an audit history, you want to store the whole row. Otherwise, the queries necessary to parse your audit table get to be hideously complicated and people spend a lot of time trying to reconstruct the state of a row at a particular point in time, often introducing errors.
If you need an audit history, I would also tend to look into Oracle's auditing features or something like Workspace Manager that automatically tracks a version history for rows. Both of those are built into the database, which tends to make them a lot easier to deal with than a custom trigger solution.
