Appian logs - Data changes

Hi,

Is there a way I can see on Appian logs as to who has made changes to the data.. for eg.. who created a certain record, who updated it, who deleted it and so on.. i tried looking for this info in tomcat-stdOut.log but cudn't get.. or do I need to create/code my own history table where I should track these user actions?

thanks in advance
