Was trying to get a forecast from Enterprise Miner to predict sales/sku for a particular store. My dataset has 3 columns, Date, SKU and Sales Units. Once I put the TS Data prep node I keep getting the error "invalid time interval". I've tried automatic, daily, weekly but no good. My dates are daily from 2017/1/29 to 2018/1/18. Any suggestions would be greatly appreciated.
