Is there a way to limit vacation rule assignment?

Hi Guys,

With vacation rules, as you know... when somebody sets this up, it delegates authority to the person they nominate. And when they perform this action, it gives the selected person their full approval authority which is standard Oracle functionality.

Is there a way to limit this in some way? So that when the person sets up vacation rules, it can only select people that have the same approval limits or higher?

thanks in advance,

Adam
