Unable to use *Keygeneration* property

Hi All,

I am trying to use Keygeneration property under remote system.

Selected Keygeneration as QualifiedRange. and selected lookup field (Say

Department Number) but i am not able to see any lookup values in the qualified

range property.

Finally i am not able to give keygeneration values for lookup values.

Can anyone tell me the solution for above problem?

Cheers

Narendra
