    System.error.java.lag.OutOFMemoryError: Java heap space

    sahar mehdizadeh

      I have created a flow in Tableau prep which requires to run 54 calculation fields. I am only able to have 13 calculation field to run the flow. when I add more calculation field, I face an error says: "System.error.java.lang.OutOfMemoryError: Java heap space" and then no output will be shown. 


      My system is 64-bit with 4.00 GB RAM / windows 7.


      How can fix this error?  If the solution is increasing java heap space, how can I increase the space for tableau prep?
