I am trying to add the following descriptive flexfields to an inventory organization parameters:

   1st level - Independent  -    Region

   2nd level - Dependent    -    Zone         , depending of Region

   3th level - Dependent     -    Subzone   , depending of Zone

When I try to associate the dependent DFF "Subzone", the system only shows independent DFFs as "Region"; but I need to associate to "Zone" wich i can´t  make it possible... Any Ideas?

Thanks in advance
