Restricting Characteristic Values based on Material

Hi all,

We have a CLASS assigned to several Materials. We have a requirement where we need to show specific characteristic values for a given characteristic based on the Material to which it is assigned.

For example, if there is a characteristic called "COLOR" with values Voilet, Indigo, Blue, Green, Yellow, Orange and Red; Material M1 should be allowed only Voilet, Indigo and Blue while Material M2 will be allowed for Green, Yellow, Orange and Red.

I checked the OBJECT DEPENDENCIES and PRECONDITIONS; but most of them are dealing with assigning one char value based on another characteristic.

Any help is highly appreciated.

Thanks

Shashi
