Track Field Changes

###Set up the database for tracking field changes

This section explains the steps necessary to set up each Table in the database for auditing. After completing these steps, the plug-in will be able to track the changes to field values in the database. (Note: You may also want to implement the validation options described in the Preventing database modification if CNS Audit is not present subsection of the Optional Set Up Tasks section at this time.) If your solution consists of multiple files, you will also need to follow the instructions in the Setting up Multiple Files / Data Separation Model section.

  3. Add a new Text field named CNS Audit Trigger. Make sure the field is named CNS Audit Trigger exactly.
