past

The past analytic creates a historical set of events by removing the current event from the set of a rule.

Syntax

past(event.property)

The following table describes the required and optional arguments:

Argument	Required Optional	Description
event.property	Required	The event property other than the latest event.

Example

when 2 transactions t with past(t.amount) as result= 15 then response with body =”${result}”

The following table describes the result for the event property value that you pass:

Event Property Value	Description	Result
amount[1]=15 amount[0]=20	The past event value should be 15.	15
