I am working on 9.3 Tableau version. I have data coming monthly in excel file . I created extract with first file and then tried Appending from rest of the monthly files but is not loading any rows nor is it throwing any error. it just
says 0 rows added even if I have same fields in all the files I'm trying to join.
second option I see is to write a custom query in tableau
ABC_ < month name> (is File name- which is data source ) .
Application ( is sheet name - which tableau treats as table )
