In Workday Adaptive Planning, when an account is deleted from the model, all associated formulas and data stored in that account are permanently and irreversibly deleted across all versions and all levels. There is no automatic transfer, reassignment, or archiving mechanism. The system does not migrate data to sibling accounts or parent rollups upon deletion. This is a critical and irreversible action - once the Rent account is removed, its historical actuals, plan data, and any formulas are permanently lost from the model. This behavior underscores the importance of data backup and version control before performing structural changes. Administrators should export or archive data before deleting accounts. The rollup account Total Operating Expenses will continue to function but will now only aggregate the remaining child, Salaries. Any reports or dashboards referencing the deleted Rent account will return errors or blank values.
