You can validate multiple mappings without fetching them into the workspace. To validate multiple mappings you must select and validate the mappings from either a query results view or a view object dependencies list.
If you use the Repository Manager, you can select and validate multiple mappings from the Navigator.
You can save and optionally check in mappings that change from invalid to valid status as a result of the validation.
To validate multiple mappings:
Select mappings from either a query or a view dependencies list.
Right-click one of the selected mappings and choose Validate.
The Validate Objects dialog box displays.
Choose whether to save objects and check in objects that you validate.
