To use a Target time series dataset , you need the historical time-series demand data for the retail items (timestamp , item_id , and the target field demand )

example: you want to forecast the demand for shoes and socks based on a store's previous sales. In the following target time series dataset, store is a time-series forecast dimension, while demand is the target field.
