'Changes from any value to new value' operator

This table shows the syntax for rules that use the 'Changes from any value to new value' operator:


Syntax	[Attribute] [Operator] [New Value] [optional Condition]
Attribute	One of the document attributes selected for monitoring. See Monitor rule - value change.
Operator	Changes from any value to new value
New Value	A constant value for the attribute that is monitored.
Condition (optional)	A monitor condition from the list of predefined conditions. See Monitor rule - value change.
Evaluation if Operator = Changes from any value to new value	Evaluates to True if one of these conditions is met: An instance of the document with [New Value] has occurred. An instance of the document with a different value than [New Value] has occurred, followed by an instance of the document with the [New Value] for the attribute monitored. If a Condition is specified, only the document instances for which the Condition evaluates to True are considered for evaluation. There is no time limit for the evaluation of this monitor. In case of repeated values changes, the monitor creates an alert each time the Attribute value becomes the New Value.

This table shows when alerts are generated:


Document instances	Alert is generated
First document instance contains the Attribute with the specified [New Value].	Yes
First document instance with Attribute value [New Value] directly followed by another document instance with Attribute value [New Value].	Yes (see also Note below)
First document instance with Attribute value [New Value] directly followed by another document instance with a different Attribute value.	Yes
Document instance with a different Attribute value directly followed by another document instance with Attribute value [New Value].	Yes
Several document instances with a different Attribute value followed by a document instance with Attribute value [New Value].	Yes
Several document instances follow each other with the attribute value alternating any value and [New Value] at different moments in time.	Yes (alert is generated each time the Attribute values becomes [New Value])

Note: If several document instances are received with the same CreationDateTime and the Attribute value [New Value], an alert is generated for each document instance. If several document instances are received following each other, but with different Creation Date Time and the Attribute value [New Value], then only one alert is generated.

Example - Changes from any value to new value

Sales orders can be "blocked" for various reasons during processing. If you do not want to monitor for a specific status transition, but only want to identify when a sales order has become blocked, you model a rule to check for a status change from any value to value "blocked".

This table shows the syntax of the rule:


Attribute	Status
Old Value	N/a
Operator	Changes from any value to new value
New Value	Blocked
Within	N/a
