Generating debugging information for transformations

If you run a transformation and it does not generate the output that you expect, you can specify that the transformation generate a log file. A log file provides information about the source elements, the target elements, and the rules that the transformation applies to transform the source elements. If the transformation transforms many elements, you might experience decreased performance while the transformation generates the log file; therefore, you should only generate a log file for debugging purposes.

About this task

To generate a log file for a transformation:

Procedure

  1. In the navigation view, right-click a transformation configuration file; then click Open.
  2. On the Main page, click Generate a debug log.
  3. Click File > Save.

Results

The next time that you run the transformation, the log file is generated as an XML file in the folder that you specify in the transformation preferences. If you do not specify a location for the log files, the transformation generates the log file in the .metadata folder in your workspace.
Tip: To set preferences for transformations, click Window > Preferences; then expand Modeling and click Transformations.
