q= timeseries q generate 'sum_Sales' as ‘Forecasted_Sales' with (dateCols=(‘Date_Year’, ‘Date Quarter’, "Y-Q"), partition='Region', seasonality=4);

q = timeserles q generate 'sum_Sales’ as 'Forecasted_Sales’ with (length=12,dateCols=("Date_Year', ‘Date_Month', "Y-M"), partition='Region');

q = timeseries q generate 'sum_Sales' as 'Forecasted_Sales' with (dateCols=(‘Date_Quarter’, 'Date_Month’, "Q-M"), partition='Region’, ignoreLast=true);
