“January” even though you just selected “February”) so a bit of confusion might ensue.ģ.
Con: the input node retains it’s name (e.g. Con: a bit more manual, scheduling of flows (when available) won’t automatically pick this up. Pro: you know which file you just selected, so no second-guessing. Simply point Tableau Prep to the new file instead.

(or move the old file to archive directory) Add the new input files to the directory and remove the old files Con: it’s a bit harder to keep track of the files and you may find yourself asking, “Did I replace it already?” “Is that last month’s file or this month’s?”Ģ. Pro: when scheduling is released in future versions, you won’t have to do anything other than replace the file and let the flow keep running on it’s schedule. In my experience, you may have to click the refresh button in Tableau Prep Pro: all you have to do is just open the Tableau Prep, run the flow it and it should work fine.

That is, literally replace the old file with the new input file of the exact same name (archiving the old ones is probably a good practice). Stick with the same filename month after month.
