Step 4. Verify order of rule execution

Step 4. Verify order of rule execution

If you create multiple field rules, confirm that the rules run in a logical order.
To review the order in which the rules run, you can view the rules in the
Field Rules
area. The
mapping
task runs the rules in the order in which the rules appear. If the order of the field rules is incorrect, you can rearrange the order.
You also can preview the incoming fields for the transformation based on the rules that you have created in the Preview Fields table. The Preview Fields table lists all included and excluded fields. For example, if you create a field rule that excludes binary fields, the
Excluded Fields
list shows the binary fields as excluded from the transformation.
If the Source transformation in the mapping uses a connection parameter or a data object parameter, the Preview Fields table does not display the transformation incoming fields.
The following image shows the Preview Fields table:
The Preview Fields table at the bottom of the Field Rules area lists the included and excluded fields.
