Note
Entire Data Properties are evaluated before anything else, such as Preprocessors,
Delimiters and Boundaries in the Settings pane (see "Data source settings" on
page92). This means these properties cannot read information from the data sample or
from any records. They are mostly useful for static information such as folder locations or
server addresses.
Preprocessor
The Preprocessor subsection defines what preprocessor tasks are performed on the data file
before it is handed over to the data mapping workflow. Preprocessor tasks can modify the data
file in many ways, and each task runs in turn, using the result of the previous one as an input.
l
Name: The name to identify the Preprocessor task.
l
Type: The type of Preprocessor task. Currently there is only one type available: script.
Preprocessor definition
l
Expression: Enter the JavaScript code to be performed on the data file. See
"DataMapper Scripts API" on page228.
Extract step properties
The Extract step takes information from the data source and places it in the record set that is
the result of the extraction workflow. For more information see "Extract step" on page118 and
"Extracting data" on page96.
Description
This subsection is collapsed by default in the interface, to give more screen space to other
important parts.
Name: The name of the step. This name will be displayed on top of the step's icon in the Steps
pane.
Comments: The text entered here will be displayed in the tooltip that appears when hovering
over the step in the Steps pane.
