Foreign Currency Payments through DI Server (SOAP)

Question

Hi All,
I am using the DI Server SOAP interface, and I am trying to add an IncomingPayment in EUR (our system currency is GBP). I have noticed an issue when trying to do this: It cannot be done unless there is a global exchange rate set for that currency on the document date, no matter what fields I populate in the IncomingPayment. This presents a problem, since although there is a GetCurrencyRate function, there is no SetCurrencyRate function that I can find...
We are using SAP 8.8 PL12 currently.
My SOAP message (which works perfectly when a global exchange rate is set for the day):
<?xml version="1.0" encoding="utf-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
     <env:Header>
          <SessionID>8E03AABD-5D5C-4551-8805-091EB75D010B</SessionID>
     </env:Header>
     <env:Body>
          <Payment>               
               <DocType>rCustomer</DocType>
               <DocDate>2011-02-22</DocDate>
               <CardCode>EXAMPLE</CardCode>
               <DocCurrency>EUR</DocCurrency>
               <DocRate>1.24</DocRate>
               <CounterReference>payment</CounterReference>
               <Remarks>test 01</Remarks>
               <TaxDate>2011-02-22</TaxDate>
               <CashAccount>153000</CashAccount>
               <CashSum>100.00</CashSum>
               <PaymentInvoices>
                    <PaymentInvoice>
                         <DocEntry>52</DocEntry>
                         <DocRate>1.14</DocRate>
                         <InvoiceType>it_Invoice</InvoiceType>
                         <AppliedFC>100.00</AppliedFC>
                    </PaymentInvoice>
               </PaymentInvoices>
          </Payment>
     </env:Body>
</env:Envelope>
Is there a way of setting the global currency rate through the SOAP interface that I have not spotted? Or is there a particular set of fields that can be populated in an IncomingPayment that allow it to be processed despite the lack of a global exchange rate?
Thanks in advance for any help!
