You can preview the results for the business logic that you apply to a mapping specification during mapping specification development.

When you edit a mapping specification, you can preview the data for the mapping specification objects that you add or edit. The Analyst tool previews the data in the mapping specification target. After you preview the results of the mapping specification, you can load the results to a target.

When you create a mapping specification, you can preview the data in the sources and target you select. When you select a transformation object and perform a data preview, the Analyst tool returns a data preview for the transformation object and any transformation objects added before this object.
