Overview
Versioning is used to manage changes to variable groups after a project has started. Tracking these changes can complicate the management of the project.
Before enabling the Versioning feature in your project, it is recommended to talk to a StudyTRAX Support Representative to determine if versioning is needed in your project.
Versioning Notes
- When versioning is enabled in a project, you can't change a published variable group, you can only make a new version
- Upgrading a subject's encounter or subject update page, will upgrade all of the subject's variable groups to the latest version
- If a new variable group is added, existing encounters will need to be upgraded to get the new variable group
- An interval expression is not versioned and must be compatible with each variable group version
- If a variable is used in the interval expression, do NOT delete or make that variable inactive
- Do NOT add variables into the interval expression that are not in every version of a variable group
