Object dependency doesn't work for class type 001.

Dear All,

I would like to use classification for picking up material.

I set up a class with class type 001 and assign to material.

When I use mm03 to search the material with class, the object dependency in the characterist doesn't work.

Does the object dependency work for the class type 001?

The example is as below.

If the characteristic CH_CAR = '01', then the characteristic CH_COLOR can show Red and Write.

If the characteristic CH_CAR = '02', then the characteristic CH_COLOR can show Black and Blue.

I wrote a depency precondition for this scenior, but it does't work.

If I change the class to type 300 and attached to a configurable material, then when I create a sales order and configure the material, and the dependency did work.

Does the object depency only support the class type 300?
