Model builders can view a detailed history for an entire model, or a single data cell in a module or dashboard. Details include a description of the change, and the user who made the change.
If your model is in standard mode, you can select the Save Options checkbox to save the model history export as an action.
You can only view up to 1000 model changes in the History dialog. If the number of changes are more than 1000, only the most recent 1000 changes display. To see all the changes, select Export to download the full list as a text (.txt) file.
A model's history is retained for the lifespan of the model.
