Preview and Save Output
We are now ready to preview and save the output of each target component. When multiple target components exist in the same mapping, you can choose which one to preview by clicking the 
button. Only one component at a time can have the preview enabled. To view and save the output of the intermediate component MergedLibrary, follow the instructions below:
1.Click 
in the MergedLibrary component.
2.Click the Output button at the bottom of the Mapping pane.
3.In the Output menu, click Save Output File if you want to save the output to a file.
To view and save the output of the FilteredLibrary component, take the steps below:
1.Click 
in the MergedLibrary component.
2.Click in the FilteredLibrary component.
3.Click the Output button at the bottom of the Mapping pane.
4.In the Output menu, click Save Output File if you want to save the output to a file.
You have now finished designing the mapping which has two target components. For further information about working with pass-through components, see Chained Mappings. For your convenience, the mapping design in this tutorial is saved as Tut3_ChainedMapping.mfd.
