I'm trying to import 'Dates' from a.csv file's 'Date column' into tableau. However, certain dates in the tableau are missing. In tableau, I don't have any filters.
Image below: Dates are grouped as 'Forecast' and 'Historical' in the Excel file. Only historical dates are displayed in Tableau, whereas forecast dates are imported as NULL. The dates column in the.csv file is all structured as a date.
Please assist me.
