I can't able to change the Item model group

Hi Friends,

While trying to change the Item model group below message was triggering

You cannot change the item model group because that would cause the Inventory policy to be changed.

How and where could i navigate and change the Item model group ? If i change any impact will cause ??

Thanks.

You are, I guess, trying to change a product that is currently non-stocked into one that is stocked. This is not a supported process, you have to create a new release product.
