I am creating a Sales Delivery against a Sales Order using an SDH import template.  The delivery has invoice elements on it for freight.  The delivery is getting created successfully, and the invoice elements (INVDTAAMT) are populated properly, but the corresponding SFOOTINV record is not being created.  If I manually go into the delivery after it is created and click Save, it creates the SFOOTINV record, but not during the import process.  Does anybody know what is causing this, and how to correct it?
