Locking the Data Definition

There are two important eventsan incident that disrupts the normal flow of any process that generates the time series. Examples of events are holidays, retail promotions, and natural disasters. that occur when you open Overrides.

• When you first open Overrides after running a pipeline, the data definition for the project is locked. The data definition includes the role assignments for the time, dependent, and BY variables, and the settings for imported attributes. The assignments for independent variables are not locked. After the role assignments are committed, you can no longer change these settings for this project.

  Make sure you are satisfied with the variable assignments before opening Overrides for the first time. After the data definition is locked, if you determine that you need to change these role assignments, you can create a new project using the same data source with different settings.

• Every time Overrides is opened, it checks for any changes to the champion pipeline output. If updates are found, you are prompted to refresh the overrides data. If you refresh the data, any applied overrides must be resubmitted and any pending overrides are deleted.

  If you have made any changes on the Data tab or in Project Settings, you should select Yes to update the data in Overrides.

After Overrides has been opened and the data definition is locked, you can still work with pipelines, adding or removing new models, or changing settings for the models. After completing your changes, make sure all of your pipelines show a status of Successful and the best champion pipeline is selected before returning to the Overrides tab and refreshing the data.
