Creating Time Series Mining Structure with DMX

Hi.I´m trying to create a mining structure with the next dmx code:[code="sql"]CREATE MINING MODEL [Cassandra]( [CompanyNK] TEXT KEY, [Date] Date KEY TIME, [Total Value Mes] Double Continuous Predict, [New Items Month] Long Continuous, [Number Branches] Long Continuous, [Number Clients] Long Continuous, [Number Salesman] Long Continuous)USING Microsoft_Time_Series(AUTO_DETECT_PERIODICITY = 0.8, FORECAST_METHOD = 'MIXED')WITH DRILLTHROUGH[/code]And i get the following error: Error (Data mining): Usage of all non-key columns in the 'Cassandra' mining model must be set to PredictOnly.This works because i already used this structure in SSDT, and it worked without having anything as predict only.Can someone help?Thanks in advance
