You can edit one or more existing transformations to modify their mapping as required.
Click the Transformation View, and select the transformation that you want to edit.
On the Transformation menu, click Open.
Alternatively, right-click the transformation, and select Open or double-click the transformation to open it. Also, you can right-click the source schema or target schema under the selected transformation, and select Open Transformation.
To modify the classifier mappings, click the ClassifierMap Designer, and make the required changes in the transformation. Double-click one of the classifiers to open the FeatureMap Designer and modify the feature mappings in the transformation as required.
Note: DDW allows you to undo or redo any action. However, the undo and redo actions are specific to the ClassifierMap Designer and the FeatureMap Designer. For example, if you made any changes in the ClassifierMap Designer and the FeatureMap Designer, and you click Undo in the ClassifierMap Designer, then only the last action that was performed in the ClassifierMap Designer is reversed. Once you save the changes, these changes cannot be undone.
On the Transformation menu, click Save to save the changes made to that transformation.
To save changes in all the transformations, click Save All.
