EagleML Message Headers

There are two main types of EagleML messages and there is a high level of relationship between their message headers:

1. Control Messages (also known as CMs or RunTaskRequest (RTRs)):

Message level header is very important for control messages.
Transaction level header is omitted in control messages.
For more information, see Format the Control Message Header.

2. Data Messages:

Data messages should contain a Transaction level header.
Some of its nodes may be involved in processing logic (this varies for different objects).

The headers for control messages and data messages have common elements that are encapsulated in most base type MessageHeader. However, they also have specific elements based on the purpose of the message to reflect integration patterns such as Message ID, Correlation ID, and Message Address.

While Message level is important for control messages, for data messages, it would have most of its elements optional.

Transaction Level Header for Data Messages

This table describe the transaction level header for a data message.

Node	Description	Optional/Required

Node	Description	Optional/Required
transactionDate	Transaction date	optional
batchKey	Contains information on the so-called batch key used to group data (EntityID^EffectiveDate^sourcename)	usually optional but required when you load Warehouse objects in batch mode.
subBatchKey
action	Defines whether to add, delete or update data in database (ADD, DELETE, UPDATE)	optional
correlationId	Unique message identifier processed and displayed by Message Center	optional
businessTaskId	Business task identifier processed and displayed by Message Center	optional Allows the use of special symbols: ~ ! @ # $ % ^ _ + / \ } [ \|\| ] { : ; - * (This is not recommended).
sequenceNumber	Defines file number in the sequence	usually optional but required when you are using Sequencer
isLastInSequence	Makes the Sequencer turn off after processing this file, if its value is TRUE.	usually optional but required when you are using Sequencer
totalCount	Counter	usually optional but required when you are using Sequencer
objectType	Router sends the message to a specific rule according to this node. Case-sensitive node.	required
objectId	Object Identifier	optional
objectDescription	Object description	optional
updateTimestamp		optional

codeTranslations		If codeTranslations node contains ‘primaryExchangeCode’ – `<codeTranslations>primaryExchangeCode</codeTranslations>` then Primary Exchange Code value (<primaryExchangeCode> node will be mapped to the Code Translation lookup pan-lcode-translation.htm as incoming value for tag 1176 (From Code Value). The output value – tag 1103 (To Code Value) will be mapped to GenericSMF stored procedure and Security Resolution logic (to tag 1981 and tag 17) if this value is not null. This logic supports the following inbound interfaces: GenericSMF, Underlying Model of GenericSMF and Forward SMF AccountingSMF MultilegSMF UnderltingSMF DeleteSMF SMF MI AccountingCA GenericCA CancelCA MandatoryCAExclusion VoluntaryCAElection AnalyticEquity AnalyticFI GenericIssueAnalytic SMFIdentifiers SMFIdentifier ReferenceElementOverride IssuePrice ExchangePrice IssuePcPrice IssueFxRateDemand Rating RecoveryRate IssuerRole IssuerRole – delete rule IssueVariableRate ModelPrice NaicDesignation Schedule SecurityNotes SecurityOverrides TimeSeries VendorCashFlow
