Interfaced receipts not populating Manufacture and Model in AM

We receive assets but the RECV_02 process creates assets without Model.  Did I miss a configuration?  Am I expecting too much from the system?

We're processing receipts from a warehouse-type source.  We create Items within PeopleSoft and the valid item list is sent to the WMS system.  The PO and Receipts are processed into PeopleSoft via the delivered loader tables.  The Receipts are populated on the BCT_CTL and BCT_DTL as 0104 transactions.  We populate INV_ITEM_ID on the PO and the Receipt.  PO_RECVLOAD does not populate the Model on RECV_LN_ASSET but it displays on Purchasing > Receipts > Add/Update Receipts.  Okay, fine.  As long as it does what it shows.
