Use of Component Group Mapping

Summary:

Customer has a requirement to have different cost elements for raw material, ingredients, packaging, etc.

We're looking for a way to automatically map the predefined cost component codes to the appropriate cost element based on the item classification when the item is received regardless of whether it's a PO receipt, Miscellaneous receipt, or Inter-org Transfer.

For example, if the item is classified as a packaging item we want the ITEM_PRICE to map to packaging cost element, ingredient cost element for ingredients, and so on.

I know we can create more than one component group mapping but what's not clear is how to link that to an item.
