Hello Pragathi,
It tries to parse a number for some of the values but the value is not a valid number:
Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: java.lang.NumberFormatException: For input string: "ProductNR,Time,Stops
What you can check is to first import your csv in an excel and check the column that is mapped on ProductNR.Time.Stops and check if all the values are valid, if not then it is the question if the data is corrupt or that you need to change your attribute datatype to string maybe
Hope this helps,
Good luck!
