mapping configuration will try to retrieve data from the file or database, using its own Data
Model and extraction logic.
After opening a data mapping configuration, data file or database, the Data Model pane at the
right hand bottom shows the data fields that occur in the data.
The Value column displays data from the first record in the data file. Use the First, Previous,
Next and Last buttons to browse through the records, or use the Page Up, Page Down, Home
and End keys.
Note that when data is loaded directly from a file or database, all values are strings.
Designing a template without sample data
Strictly speaking, you don't need sample data to design a template; the only thing you really
need in order to add variable data fields to a template is a Data Model.
You can open a Data Model without data by importing a Data Model file, a JSON file or a
Connect template file from within the Data Model pane, using the top-right icon: . The file's
data model structure will be displayed in the Data Model pane, but the data is not included.
You can also add fields and tables and set default values for fields in the Data Model pane; see
"Changing the Data Model" on page1055. This way you could even build a Data Model in the
Designer from scratch.
However, without sample data you won't be able to preview the template with actual data in the
Designer.
Tip
It isn't possible to enter values directly in the Data Model pane, but there is a workaround:
click the JSON Sample Data toolbar button on the Data Model pane. You will see a
JSON string that represents a single record based on the current Data Model, with
dummy values (like empty strings and zeros). Edit that JSON string and click OK to insert
the data in the Data Model.
