More than one class type for a Material

Hi All,

We have a requirement of using a Material for Variant configuration. So we need to assign Class type 300 for that Material.

But that Material is Batch managed. So Class type 023 is already assigned. I am unable to extend the Material to Class type 300.

I searched forum, it is given that, it is possible to maintain different Class types for a Material.

But I tried, I couldn't do that.

Please help me to extend a Material to another Class type.

Regards,
