Creating Netlist Error

I am trying to create a new netlist from a file that I modified in OrCAD capture.  When I run tools > create netlist  the following error occurs: Error: Schematic supports creating XNets for passive devices and for devices having XNET_PINS properties but the Layout will create XNets only for devices having XNET_PINS properties. Change setting in Layout or Schematic, re-generate files, and re-run the flow.

I am modifying a previous .brd version and I don't understand how to change the settings in Allegro PCB to get rid of this error.

Thanks for the help
