ID:19824 A Preservation Level setting cannot be applied to the root partition. Remove the preservation assignment associated with the root partition before recompiling the design.

CAUSE: You have assigned a Preservation Level to the root partition of a design. This is equivalent to preserving the entire design.

ACTION: Remove the Preservation Level assignment associated with the root partition of the design to avoid this error. If you wish to start the compilation flow from a later stage for the full design, use the Compilation Dashboard or individual command-line executables to run the appropriate stage (for example, to preserve the entire post-synthesis design while making Fitter setting changes, you can start the compilation from the Plan stage of the Fitter).
