Setting the Optimizer Level for a Developer Tool Mapping

When you run a mapping through the Run menu or mapping editor, the Developer tool runs the mapping with the normal optimizer level. To run the mapping with a different optimizer level, run the mapping from the Run Configurations dialog box.
    1. Open the mapping.
    2. Select Run > Open Run Dialog.
    The Run Configurations dialog box appears.
    3. Select a mapping configuration that contains the optimizer level you want to apply or create a mapping configuration.
    4. Click the Advanced tab.
    5. Change the optimizer level.
    6. Click Apply.
    7. Click Run to run the mapping.
    The Developer tool runs the mapping with the optimizer level in the selected mapping configuration.
