    Tableau Prep Outputs Empty Dataset

    Olivia Shen

      Hi All,


      I know Prep is quite new and not sure if anyone has ever had this same issue as I have.


      I have several outputs of a Prep flow, all with values but one. This output shows values as expected while rendering, but the actual output file has not values after I run the flow, only showing column names (see pics below).


      Output in Prep:

      Output as csv:


      I've tried different output types, but all gives empty data set. I also try to join this source with others to run the output, again, all columns from this source are just null.


      Really have no idea how it happens and it would be very much appreciated if someone could point out what the issue is.
