  Hi @Rapidminerpartner,
  
  

  2147483647 is the maximum positive value for a 32-bit signed binary integer in computing.

  
  As a workaround for now you can also use a Numerical To Real operator. They won't see the difference without going to the statistics.
  
  If this huge integer is a unique identifier (ID), it is better to be converted to polynominal. 
  
  Best,

  Hi,
  
  You cannot read it as an integer, as Integer is limited to 2^31 = 2,147,483,647 in Java.
  You can read it as a real, then it will be fine.
  
  Regards,
  Marco
