Question about cRIO 9004 resources - labview

  I am writing a FPGA VI and need to download it to cRIO 9004 to generate bitstream, I need to use LUT( look up table) in my VI as the FPGA VI cannot calculate the sine function so I need to contruct a LUT in order to do the sine calculation inside the FPGA VI. However, after I contruct 2 LUT with size 2048, it shows there is not enough resources and the compliation is failed, what is the maximum sizes of the 2 LUTs in the FPGA VI so that the FPGA resources of LUT will be enough for use.
 
  At the same time, I want to know does using LUT also consumes the FPGA resources of SLICES, not just the FPGA resources of LUT?
