Extra Week Indicator Setup View

The Extra Week Indicator Setup view allows you to set which week is the 53rd, or extra week. The measure can be selected in the Extra Week Indicator Data Source found in the Final and Source Level Parameters View - Advanced Settings.

For forecasting methods which only require demand as input, the Extra Week functionality works by setting up the Extra Week Indicator. However, there are methods that require additional inputs, like Causal, Bayesian or profile-based.

For these, the Extra Week is handled by the additional inputs. For the Causal method, it is handled by the baseline, which is an input to the method.

For Bayesian and profile-based methods, it is handled by the plan and the profile, respectively.
