Thanks for your reply and kind acknowledgement.
I've re-configured the LoadRatesFrom to 2013-11-01 in Tourplan iS LIVE wenService, which this must be done by us.
From now on, you should be able to retrieve the rates from 2013-11-01 onward via your Tariff Writer. Otherwise, you shall acknowledge us.
Please note that this setting is applying to iCom (hostconnect and webConnect) system too.
