Critical Updates

UpdateChanges to iLink On-Demand Party Details for Order Mass Cancel - Continuing This Week

† Denotes update to the article 

On this Sunday, October 11 (trade date Monday, October 12), CME Group will continue implementing iLink messaging changes to on-demand administrative information for the iLink Order Mass Action Report (tag 35-MsgType=BZ) to consistently return customer account information.

On-Demand Party Detail Definition Request Acknowledgment

Population of tag 1691-PartyDetailID for the Customer Account Party Detail Role (tag 1693-PartyDetailRole=24) on the Party Details Definition Request Acknowledgment (PDDRA, tag 35-MsgType=CY) will always reflect the value from the Party Details Definition Request (PDDR, tag 35-MsgType=CX).

Currently, the tag 1691-PartyDetailID on the PDDRA is populated only when tag 6115-MassCancelRequestType=101 (Account) is sent in the Order Mass Action Request (tag 35-MsgType=CA).

iLink Party Details Definition Request Acknowledgment
Tag 1693-PartyDetailRole	Submitted Tag 1691-PartyDetailID	Submitted tag 6115-MassCancelRequestType	Current Return Tag 1691-PartyDetailID Value Behavior	New Return Tag 1691-PartyDetailID Value Behavior
24 (Customer Account)	ABCDE	≠ 101	Not Present	ABCDE
ABCDE	= 101	ABCDE	ABCDE

This change is only applicable to on-demand administrative information. Pre-Registered Party Detail Definition Request Acknowledgment messages sent from the Order Entry Service Gateway remain unchanged.

TransactTime Precision Update

With this change, tag 60-TransactTime on the iLink Order Mass Action Report (tag 35-MsgType=BZ) will be sent with nanosecond precision. This timestamp is currently sent in milliseconds.

For details regarding submitting the new FIXML Position Message, file management, field validations, and example scenarios, please refer to the information in the CME Group Client Systems Wiki.
