Change Control

Users can create a snapshot of their instruments (i.e., .csv data dictionary) that gets stored on the Project Revision History page.

Additionally, a data dictionary snapshot is also created automatically whenever a data dictionary is uploaded on the Data Dictionary Upload page or via the API metadata import.

Good Practice

Before your project has been moved to Production status create a snapshot of your instruments. Then every time you need to make a change create another snapshot. This will allow you to revert back to an earlier version of your instruments if your change causes issues.
