Data Source
Select a report data source based on the Workday Extend business object you want to purge. Example: All Charities.
Report Tags
Select Purge.
3. As you complete the Columns tab, include at least 1 field in the report to identify the instances for which you want to purge data. Example: The Relationship Manager field on the Charity business object.
4. (Optional) To create a filter to identify the instances for which you want to purge data, complete the Filter on Instances section on the Filter tab.
Note: You must add logic to explicitly exclude purged rows from report filters or counts in WQL queries.
