Preprocessor step
The Preprocessor step allows the application to perform actions on the data file itself before it is
handed over to the Data Mapping workflow. In addition, properties can be defined in this step.
These properties may be used throughout the extraction workflow. For more information, see
"Preprocessor step" on page279.
Adding an extraction
In an extraction workflow, Extract steps are the pieces that take care of the actual data
extractions.
To add an Extract step:
1. In the Data Viewer pane, select the data that needs to be extracted. (See "Selecting data"
on page261.)
2. Choose one of two ways to extract the selected data.
l Right-click on the selected data and select Add Extraction from the contextual
menu.
Note
For optimization purposes, it is better to add data to an existing Extract step
than to have a succession of extraction steps. To do that, select that step on
the Steps pane first; then right-click on the selected data and choose Add
Extract Field.
l Alternatively, drag & drop the selected fields into the Data Model pane.
Tip
In a PDF or Text file, use the Drag icon to drag selected data into the
Data Model.
With this method, a new Extract step will only be added to the extraction workflow if
another Extract step is not currently selected. Otherwise, the field is added to the
currently selected Extraction step.
Dragging data into an existing field in the Data Model will replace the data. The
