Custom properties can be added via the Preprocessor step; see "Preprocessor step" on
page258.
A property-based field cannot be added directly. To fill a field with the value of a property, you
have to change an existing field's Mode to Properties.
1. Select the field in the Data Model.
2.
On the Step properties pane, under Field Definition, change its Mode to Properties.
3.
Select the property from the Property drop-down list, or click the button to the right, to
open a filter dialog that lets you find a property based on the first few letters that you type.
Another way to add the value of a property to a field is by setting the field's Mode to JavaScript
and entering the corresponding property in the Expression field, e.g.
data.properties.myProperty;.
Adding fields dynamically
Outside of the DataMapper the Data Model cannot be changed. It isn't possible to add fields to
it when using the data mapping configuration in Workflow. It is however possible to add data to
existing fields via Workflow; see "Adding fields and data via Workflow" on page273.
Editing fields
The list of fields that are included in the extraction, the order in which fields are extracted and
the data format of each field, are all part of the Extract step's properties. These can be edited via
the Step properties pane (see "Settings for location-based fields in a Text file" on page346).
Renaming and reordering fields in an extraction step
The names of fields, as well as the order of fields in an extraction step, can be changed via the
properties of the Extract step that they belong to.
1. Select the Extract step that contains the fields that you want to rename. To do this you
could click on one of those fields in the Data Model, or on the step in the Steps pane.
