Supplier Managed Inventory (SMI) and Material Burden

Well, this one threw me for a loop. When receiving an SMI PO, I have the ability to enter Landed Cost values. However, when this amount is applied to the receipt, it does not increase the Material Burden.
I do need to confirm that it increases Mtl Burden for standard POs, but I am curious if this is supposed to work and if so, could I be missing something.
