As new versions of the study are created, the system will track those changes made to the subject forms.

These changes can be recorded using a customized study form.

  1. Click on the Version tab
  2. Clicking the Diff link will display the Version Difference page. 





The Version Difference page displays the differences that exist between a Source Version and a Destination Version as shown in the figure below.


Versioning applies only to the data being collected. In other words, form elements themselves. Changes made to user roles or how often forms are collected are not under the enforcement of version control.
