I'm getting a SOAP Error from a get suppliers request, the <soap:Body> is: <GetSupplier xmlns="Kashflow"> <UserName>MyUserName</UserName> <Password>MyPassword</Password> <SupplierCode>CODE</Supplier> </GetSupplier> The response is a failed SOAP call with the error "There is no row at position 0" I've got exactly the same setup for customers and that code works fine, the getCustomer call returns a customer or a blank record and I'm able to take action on it.
