You may delete mappings that you no longer use. When you delete a mapping, you do not delete any sources, targets, mapplets, or reusable transformations defined outside the mapping.
If you enable version control, a deleted mapping remains checked out until you check it in. To check in a deleted mapping, click Versioning > Find Checkouts. Select the deleted mapping and click Tools > Check In.
You can delete a mapping from the Navigator window, or you can delete the mapping currently displayed in the Mapping Designer workspace.
To delete a mapping from the Navigator window, select the mapping and press the Delete key, or click Edit > Delete.
To delete a mapping currently displayed in the Mapping Designer workspace, click Mappings > Delete.
