In order to determine which users created revisions in the Solution Manager Administration Tool, I would use the below methods.
1. **By using Graphical User Interface:**
* In the Solution Manager Administration Tool, I could login as administrator or the user who has the promotion admin role and navigate to the **‘Promotions’>’Revisions’** ,In the Revisions tab I could see the user's name who created the particular revisions under the **‘Created by’** column. You could also see the user’s name who lastly modified the revision by looking into the **‘Last Modified By’** column.
2. **By using REST API:**
* By using the below API I could see all the users who created the revisions in the field **‘creationUser**’.
For more information you could refer to the [Get the list of Revisions](https://community.denodo.com/docs/html/browse/latest/en/solution_manager/administration/appendix/rest_api/rest_api#get-the-list-of-revisions) section under Solution Manager Administration Guide.
Hope it helps!
