sasCommunity Tip of the Day

You can direct SAS to keep an audit trail of all of the updates made to a SAS data set. This is particularly handy if you need to determine who updated a SAS data set at any given time for a security review or a data integrity audit. The audit trail file allows you to track patterns of when particular data were added, modified, or deleted. You may even be able to fashion your own update roll-back program from the audit file.


If you work in a security-conscious enterprise, or just want to know who, what, how and when an important SAS data set was updated, take a serious look at SAS audit trails.
