    The tableau prep file can not be read in Tableau prep

      Hi Tech,


      I have a question on Tableau Prep. I saved the following file yesterday after manage the data from two excel and saved the tableau prep as well as the output. Today I was trying map data in Tableau and want to re-manage the data in tableau prep. While I re-open the tableau prep saved yesterday, it shows me the red signal that the file can not be read. I can't believe it so I re-drill the two excel sheets from the same folder and it succeed. Please see the screenshot below. I want to know why this happened. Thanks. I don't think I have to do the same thing for every tableau sheet that's really time-consuming.
