Reference: Workforce Planning Configuration Cleanup After Deactivation

To deactivate the workforce planning configuration manager, select

Unregister Orchestration

within the Workday data source credential. After deactivation, we recommend that you delete the application-created items in Adaptive Planning in this order:

Where to Delete	What to Delete
Design Integrations	Version parameter from the planning data loader.
Design Integrations	Workday data source.
Design Integrations	Metadata and data loaders.
Design Integrations	All integration tasks except the orchestration task. You can't delete the orchestration task in Adaptive Planning Design Integrations.
Design Integrations	Workday external system.
Model Management	Plan version.
Model Management	Level assigned sheets.
Model Management	Levels.
Model Management	Level attributes.
Model Management	Dimensions. This also automatically deletes dimension attributes.
