By default, ePublisher will automatically scan your documents, thus making sure any new styles, conditions, variables, etc. are added to your project.

If you set this option to Ask, then adding a source document a dialog box will appear:

This indicates that files such as FrameMaker .book files will scan for additional .fm files linked from this source. Clicking Yes will scan the individual documents so that the document set styles, for example can be added to the Style Designer (the same goes for most of the document set customizations.)

However, you can specify that you want ePublisher to scan source documents when you add them to your project. For example, you can choose to have ePublisher prompt you to scan the source documents when you add source documents to your project, or you can choose to always have ePublisher scan source documents when you add them to a project. The scanning option you specify will become the default selection for all existing and subsequent projects.

If you choose to never have ePublisher scan source documents, when you add them to a project, you must remember to scan your source documents before you generate output.
