The content on this page explains how to manage versions of supported design objects:
All versions of an object are saved and developers can view the definitions of old versions; however, when invoked, it is always the latest version that executes.
Versions of a single object can be accessed by users with Viewer permissions, by doing one of the following:
This option opens the Versions dialog with a list of versions:
Click on the name of a particular version to open its definition in a new tab or dialog (in the case of constants and connected systems). If you're looking for a version created by a particular user or during a specific time period, use the filters to quickly narrow your search.
You can compare the latest version of any supported object type with any of its previous versions to understand and track changes in properties, definitions, security and more. To compare objects across environments, see this page.
Certain process model fields are not compared. See the list below:
To compare an older version of an object with the latest version:
The version comparison opens in a new browser tab.
Note: Sections that do not contain any changes are collapsed by default.
The changes made between the two versions are highlighted with the following colors:
|Type of Change||Color|
If you need to revert to an older version of an object, open the older version and click Save. This will create a new version of the object with the definition that is currently loaded in the designer. Modifying a previous version and saving it as the latest version does not affect the old version. To avoid confusion, you should close the tab from which you opened the Versions dialog, since it now contains an old version.
Designers with at least Editor permissions to an object can delete its versions, so long as the object has more than one version. To delete a single version, click the corresponding red X in the rightmost column of the grid. A dialog will appear, asking you to confirm that you want to delete that version
Web APIs do not support deleting versions.
To delete multiple versions, select filter criteria that return the versions you want to delete. A message will appear that prompts you to delete the filtered versions. If the Latest version is included in the filtered results, it will not be included in the bulk deletion. This allows for easier and faster cleanup of object versions, in order to maintain useful versions and prevent version buildup that may affect engine memory.
