Create Declare OnChange rules to run an activity automatically at activity step boundaries when the value of a specified property changes. This capability provides a form of automatic forward chaining.

For example, a Declare OnChange rule can update a year-to-date counter property (an integer) to track how many times a work item status changed in value. Another Declare OnChange rule can compute the average dollar amount of work items entered by a work group, in real time.

Declare OnChange rules can force all processing on a work item to be suspended pending an independent review of the situation. The independent review is supported by one or more flows. This feature can support compliance, fraud detection, and quality control staffs.

Where referenced
