Siebel adapter uses the COM interface to invoke calls on Siebel.
For business component query, Siebel supports two ways of
retrieving the field values for records. One can either use
GetFieldValue to retrieve one field at a time or the other
option is to use GetMultipleFieldValues to retrieve values for a
bunch of fields in one go. The latter is better from a
performance standpoint and is what the adapter uses. The problem
with this approach though is that even if one of the fields,
whose values are being retrieved, is mis-configured, the entire
query call fails.  In development environments, it can happen
that some of the customizations have issues, resulting in query
failure as described above. The first step towards diagnosing
the problem is identification of those problematic fields. The
error message doesn’t always help identify the fields. When in
such situation, one can use the attached Siebel COM sample code
to narrow down the fields. You will need to add a reference to
