Code undefined error when updating business partner through B1iF mobile web service

We're trying to develop an application that makes use of the B1iF mobile web services but run into issues when trying to add a business partner using the AddBP2 call.  We get an error "code undefined" back as a response.  We're using a series pulled from NNM1 that has already been defined in SAP and assuming that we can fill in any value for the cardcode.  Is there a reason we might get the DI code undefined error back from this SOAP call?
