Business Context
The primary business use case for this feature is to enable dynamic calculation of Importance and Priority fields in Work Order object, for use by the ServicePower schedule optimizer. So, this feature is supported out of the box for the target object Work Order. Enabling this feature for Work Order object facilitates use of data lookup rules for any purpose, in addition to importance and priority calculation. For instance, these rules can be used to set Work Order’s Billing Type and Order Type based on other attributes of Work Order.
