Data preview

To view the output of the hierarchical mapper and test the statements, you can preview the hierarchical mapper.
The input file that you can use depends on the source schema. If the source schema comes from a hierarchical schema or a data service, the input file must be an XML or JSON file. If the source schema comes from an intelligent structure model, you can also use CSV and PDF files as input files.
The following image shows the Preview page of a hierarchical mapper:

When you preview a hierarchical mapper that uses an intelligent structure model for the source schema, the input file must be the same file type as the sample file used to create the intelligent structure model. For example, if you create an intelligent structure model using a CSV file as the sample file, you need to use a CSV file as the input file to preview the hierarchical mapper.
