Update Trade Records

The UpdateRequest method updates trade records in CME STP BaCE. This is the standard update request element. You use the CME STP BaCE Transaction ID (CHTransactionID) to identify the trade to update.

An update request can contain instructions for verifying trades, rejecting trades, and updating reference numbers for trades. A single UpdateRequest element can contain multiple instructions, to both verify a trade and update its reference number. The order of the instructions in the UpdateRequest element determines the order in which CME STP BaCE performs them.

Elements

The UpdateRequest element has the following elements:

Child Element	Description

Child Element	Description
CHML	Standard header element.
CHRequest	Standard request element.
UpdateRequest	Standard update request element.
AcceptRequest	Verify a trade record.
RejectRequest	Reject a trade record.
UpdateReferenceNumRequest	Update a trade record with your reference number.

Although the UpdateRequest element in the XML schema contains the BrokerCheckoutRequest, UndoBrokerCheckoutRequest, TraderVerifiedRequest, UndoTraderVerifiedRequest, and UpdateUserDefinedValuesRequest child elements, you cannot submit these update requests.
