also lets you define properties and runtime parameters that can be used throughout the data
mapping workflow.
For a complete overview of the settings for a Preprocessor step, see: "Preprocessor step
properties" on page365.
Properties and runtime parameters
A data mapping configuration's properties hold data that can be used throughout the data
mapping workflow to compare against in conditions or to complement the existing data.
Runtime parameters are properties that will pass information from OL Connect Workflow to the
data mapping configuration.
For more information see "Properties and runtime parameters" on page253.
Preprocessors
The Preprocessor step can contain any number of preprocessors. They will be run in sequence
before the data is sent to the data mapping workflow.
A preprocessor could remove certain records altogether.
One example of how a preprocessor could be used is given in a How-to: Using Preprocessors
in DataMapper.
Note that preprocessors are not executed automatically while designing the data mapping
workflow; you must therefore execute them manually. The reason for this is that preprocessors
can potentially be quite lengthy operations that would hinder the automatic refresh of the
display whenever anything is changed in the data mapping workflow.
To add a preprocessor:
1. Select the Preprocessor step on the Steps pane.
2.
On the Step properties pane, under Preprocessor, click the Add button .
3. Under Preprocessor definition, add the script. Preprocessing tasks must be written in
JavaScript (see "Using scripts in the DataMapper" on page411 and "DataMapper Scripts
API" on page408).
