RDF - Seasonal forecast method

Hi,

I'm trying to understand seasonal forecasting method.

We're using RDF version 14.1.1.14

In Forecast Admin WB we've forecast methods seasonal , multiplicative seasonal and additive seasonal.

But not understanding the link between them.

RDF user guide says SeasonalES is combination of several Seasonal methods.

This method applies the Multiplicative Seasonal model unless zeros are present in the data, in which case the Additive Winters model of exponential smoothing is used.

But there is not SeasonalES method present in Forecast Admin WB.

Also RDF has forecast method AutoES in which there are below 2 sub methods.

Multiplicative Winters Exponential Smoothing -->RDF now offers a choice of four different forecasting approaches within the Multiplicative Seasonal Forecasting Method.
