Referencing Coordinate Systems
 

I want to create a Field Fuction which look like that:
($$Position(@CoordinateSystem("Laboratory.CooPost" ))[0] < 8.9)?1:0


The error messages refer to the Postion definition, especially to the Coordinate System. I write it like described in the user guide and try different other spellings, without success. Is there anybody who know how to write it correctly?

Try ...

($${Position}(@CoordinateSystem("CooPost"))[0]<8.9)?1:0
