Scenario:How validate all mapping in repository ?
- In repository go to menu “tool” then “queries”. Query Browser dialog box will appear.Then click on new button.
- In Query Editor, choose folder name and object type as I have shown in the picture.
- After that, execute it (by clicking the blue arrow button).
- Query results window will appear. You select single mapping (by selecting single one) or whole mapping (by pressing Ctrl + A) and go to "tools" then "validate" option to validate it.
