Use
If you want or need to protect especially critical data, it may be advisable to activate the change document for this data. This function logs changes made to infotype records.
Integration
The change document has nothing to do with the authorization check. It does not prevent unauthorized users from accessing data. Rather it logs attempts made by unauthorized users to access data. You can evaluate the changes using the RPUAUD00 report (Logged Changes in Infotype Data).
You can activate the change document in the Implementation Guide (IMG) for Personnel Management under Personnel Administration ® Tools ® Revision ® Set up change document. For more information about the change document, see the documentation on this IMG activity.
