¶ 1. Overview
The actions performed in T6 Scenarios are recorded through the Scenario section of the main menu (available from version 12.3 onward), such as simulations, data copying between scenarios, and scenario data cleaning. T6 stores all actions performed by the user for creating, copying, cleaning, moving, or simulating in the scenario.
¶ 1.1. Prerequisites
To use this tool, the user must have the following Manager Functionality enabled in Permissions:
It is also necessary to enable the following Preview Features:
All three Preview Features above must be enabled for full Scenario History functionality in T6 Enterprise version 12.3 or later.
¶ 2. Functionalities
Through the Scenario History tool, we can view a detailed history of the actions performed from scenario creation, simulation, data copying, data cleaning, and rollback, being able to select any of the records in the listing to view its details. From this screen, we can also roll back an action displayed in the listing, as long as it does not contain errors and is not of the "rollback" type.
¶ 3. Usage
To use the Scenario History, follow these steps:
1. In the T6 main menu, click Scenario;
2. In the Scenario section, select the History option;
In versions prior to 12.3, access Scenario History through Analysis > Scenario History instead.
- By clicking on Scenario History, a new window will open in T6;
- A listing will be displayed showing all actions performed in the scenarios, with the following structure:
| Date | Type | Scenario | Context | User | Status | Actions |
|---|---|---|---|---|---|---|
| Displays the date and time the action was performed | Displays the type of action performed | Displays the affected scenario | Displays the action performed detailing the members involved | Displays the user who performed the action | Displays the status of the performed action: Error, Success... | We have 2 buttons. Copy (available in case of error). Rollback (reverts the action performed in the selected line, not displayed in case of error) |
-
We also have the following filtering options for data display:
-
Application: dropdown to select one of the existing applications in T6;
-
Scenario: dropdown to select a specific scenario. If the Application field is left blank, all scenarios with records in the listing will be displayed. If an Application is selected, the scenarios displayed for selection will be limited based on the scenarios existing in the selected application;
-
Type: dropdown to select the type of action performed in the scenario, with the following options:
-
Scenario creation: displays only scenarios created using the scenario creation tool in the Scenario section of the main menu;
-
Simulation: displays only scenarios altered using the scenario simulation tool in the Analysis section of the main menu;
-
Data copy: displays scenarios that copied data from another scenario using the Scenario Data Copy tool in the Scenario section of the main menu;
-
Data cleaning: displays scenarios that had data removed using the Scenario Data Cleaning tool in the Scenario section of the main menu;
-
Rollback: displays only rollback actions performed from this screen;
-
Rolled back records also appear in the filtering, following the type that originated the record.
- User: dropdown to select a specific user;
-
Filtering can be performed individually or by combining the above options.
After performing a rollback, the rollback record will be created and displayed in a new line. The rolled back record will continue to be displayed in the listing, but with its data crossed out:
3. To view the details of a specific record, double-click the selected line;
- A side panel will open displaying the same information contained in the listing, but in a detailed way, allowing us, in case of error, to copy the generated message.
- When selecting a Rollback-type line, the View details button will be enabled. By clicking on "View details" the panel content will be replaced, and it will display the details of the rolled back action.

¶ 4. Rollback Rules
¶ 4.1. Rollback Order
Rollbacks in the Scenario History follow a strict reverse chronological order. Only the most recent action — that has not yet been rolled back — can be reverted at any given time.
When hovering over the Rollback icon of a record, a tooltip is displayed explaining why the action cannot currently be reverted.
The table below summarizes the rollback rules:
| Action | Can be rolled back? | Condition |
|---|---|---|
| Most recent action | Yes | Always available (if no error) |
| Intermediate action | No | Must first roll back all more recent actions |
| Rollback action | No | Rollback events cannot be undone |
| Scenario creation | Yes | Always available — rolls back all subsequent events |
Reverting a scenario creation action will delete the scenario and all events associated with it. Because the cube structure changes, a cube publication is triggered automatically. Use with caution.
¶ 4.2. Cross-Navigation Between Events
When a Rollback-type record is selected in the details panel, a View Details button is displayed. Clicking this button navigates the panel to show the details of the original action that was rolled back. Clicking View Details again returns to the rollback event, allowing back-and-forth navigation between a rollback and the event it reverted.
¶ 5. Limitations
¶ 5.1. Operations Tracked
The Scenario History records actions performed through the Scenario section and the Simulation action in the Analysis section of the T6 main menu. Operations performed outside these menus do not generate history entries.
The following actions generate history entries:
- Scenario creation (via Scenario > Create);
- Data copy (via Scenario > Copy Data);
- Data move (via Scenario > Move Data);
- Data cleanup (via Scenario > Data Cleanup);
- Simulation (via Analysis > Simulations);
Actions performed directly in Modeling > Designer (e.g., manually adding a member to a dimension and publishing the cube) do not generate Scenario History entries and cannot be reverted through this tool.
¶ 5.2. Structural Changes
If a new member is added to a dimension after a scenario event was recorded, the system may no longer be able to revert that event. This is because the fact table structure changes when a new dimension member is introduced, making earlier snapshots incompatible with the current structure.
¶ 5.3. Version Requirement
The full Scenario History functionality — including the dedicated Scenario menu and all three required Preview Features — is available starting from T6 Enterprise version 12.3.
Prior to version 12.3, the Scenario History was accessible through Analysis > Scenario History, and only the Scenario History preview feature was required.
¶ 6. Q&A
Frequently Asked Questions
1. Which preview features are required to use the Scenario History tool in T6 Enterprise 12.3 or later?
Starting from T6 Enterprise version 12.3, three Preview Features must be enabled for full Scenario History functionality:
2. Can I roll back any action in the Scenario History?
No. Only the most recent action that has not yet been rolled back can be reverted at a time. Rollback actions themselves cannot be undone.
The one exception is scenario creation — it can always be rolled back, as doing so reverts all subsequent events and deletes the entire scenario.
3. Why is the Rollback button not available for some records?
The Rollback button is not available for records that:
- Are not the most recent action in the sequence (you must first roll back more recent actions);
- Have an error status;
- Are themselves rollback-type events.
Hover over the rollback icon to see the specific reason why it is currently unavailable.
4. What happens when I roll back a scenario creation action?
Rolling back a scenario creation action will:
- Delete the scenario and its associated data;
- Trigger a cube publication for the affected application;
- Automatically roll back all other events (copy, move, simulation, cleanup) associated with that scenario.
This action is irreversible. All snapshot data stored for that scenario will also be deleted.
5. Do actions performed in Modeling > Designer appear in Scenario History?
No. Only actions performed through the Scenario menu (v12.3+) or the Analysis section (pre-v12.3) generate history entries. Changes made directly in the Designer (such as adding a new member to a dimension) are not tracked in Scenario History.
6. What does "View Details" do on a rollback-type record?
When you open the details panel for a Rollback-type record, a View Details button appears. Clicking it navigates the panel to display the details of the original action that was rolled back. You can click View Details again to return to the rollback event.
7. Where can I find the Scenario History in T6 Enterprise 12.3 or later?
Starting from version 12.3, the Scenario History is accessible through the dedicated Scenario section of the T6 main menu (Scenario > History). In versions prior to 12.3, it was accessed via Analysis > Scenario History.
8. Why does rolling back a scenario creation trigger a cube publication?
Rolling back a scenario creation deletes the scenario and its member from the cube structure. Because the cube structure changes, a cube publication is required to apply the changes and ensure the application remains consistent.
