Hello . Do you have a Tableau Packaged Workbook that can be shared? The amount of data in the example provided would not be enough to have Tableau generate a forecast. How Forecasting Works in Tableau might be a good place to start with learning about using Tableau's built in capabilities. You might also be interested in reading Using R forecasting packages from Tableau | Bora Beran to get more control of the data and associated forecast.
Thank you Patrick, I appreciate the response. I will look into the options you provided or post a test workbook if needed.
