To captureproposed values from a business process event, you must use anevent-related business object. For example, a Staffing Event business object can provide both the current and proposed values of job, location, or compensation during a transaction.

The Workday binder clarifies:“The report data source provides the view into the primary business object. This object gives you access to class report fields as well as links to related business objects.”. By selecting anevent-related objectas the report’s data source, you can retrieve pending changes alongside existing values.

Other answers are insufficient: “effective dating” only retrieves data snapshots, and filters cannot detect “proposed” unless tied to the correct object. Lookup Value as of Date would return historical data, not future proposed changes.
