Saved scenario history
The ETM tracks history for saved scenarios. When a saved scenario is opened, changes are made, and those changes are saved, it is added as a new scenario version to the scenario history. This history can be viewed in My Scenarios. The history includes for each scenario version: the date, the user that saved the changes (relevant when there are multiple users working on a scenario), and, optionally, an added description for the saved changes.
The scenario versions in the scenario history are different from the Model versions. Each scenario is made in a specific version of the model, but each scenario can have different versions in its history.
The following actions can be taken in the history overview:
- Open a specific scenario version: click on a specific version to open the scenario as it was at that point in the history.
- Edit the description of a scenario version: edit the description for a specific version to explain why or which changes were made.
- Restore an older scenario version: restore the scenario to a specific version in the history. This means that changes applied after this scenario version will be lost. This action is irreversible. A warning pop-up will appear as an extra precaution for this action.
Roles and rights
Depending on the user's role in a particular scenario (see also Roles), they have different rights concerning the history. This is shown in the following table.
| Role | Viewer | Collaborator | Owner |
