About Schematic and footprints in orcad..

 hi everyone,

 I am new to orcad. I am designing a PCB using orcad. I put all the components in the schematic and make the connections and I create a netlist and hence the footprint.

The questions are,

1) If I change any connection or component in the footprint then it should show the error indicating that it is not in schematic.

2) Some times i may forget some connections in the schematic. In such case if I add any new connection in the footprint then it should be applied to the schematic.
