Running the Auto Map task flow

Follow this task flow to run the Auto Map in the Design Studio.

About this task

When you start the Auto Map wizard, it takes you step-by-step through the process that automatically maps selected source and target objects.

Before you start the Auto Map wizard, you can select options in the Auto Map Preferences. These options are the default selections that the Auto Map uses. As the Auto Map wizard takes you through the process step-by-step, you can change the default selections. However, any changes to the selections that you make in the Auto Map wizard, are not saved. Subsequent runs of the Auto Map use the original default selections that you made in the Auto Map Preferences window. You can, again, change the default selections dynamically in the wizard. But, you can always update the settings in the Auto Map Preferences so that they are saved and used by the Auto Map in subsequent runs. Then, you do not have to reselect the options when you rerun the wizard. You are not required to select the Auto Map Preferences before you run the Auto Map. But, you can avoid continually reselecting the options every time you run the wizard. At any point, you can set the options in the Auto Map Preferences.

If required, you might also want to back up your map before you run the Auto Map because the Auto Map operation does not support an Undo function.

Procedure

To run the Auto Map:

  1. Open the map in the Map editor.
  2. Select two groups that you want to map automatically. One of the groups that you select must be a group component in an output card. You can select choice groups. To toggle your group selections on and off, press Ctrl, and click the selection.
    Also, select source and target objects at the levels that you want to map. If you select the top level, the Auto Map operation maps all the groups and nested groups. The Auto Map icon in the Map editor toolbar is enabled.
  3. Click the Auto Map icon. The Map Designer window opens and displays an informational message. It warns you that the Auto Map operation does not support Undo so that you can back up your map before you complete running the Auto Map.
  4. Click OK in the Map Designer window. The Auto Map wizard starts. The Auto Map window opens and displays objects under the source and target groups that you selected.
  5. Follow the wizard prompts. You can set the various options that the Auto Map operation uses to automatically map the source and target objects.
  6. Click Finish.

Results

The Auto Map operation automatically maps the selected source and target objects that are based on the matching properties and the proposed rules that you selected. The operation does not map the rule from the source to the target for the following objects:
  • Objects that you did not select to create a rule.
  • Objects for which the mapping process did not find a match.
Tip: You can run the Auto Map without using the wizard, by pressing Ctrl+A after you select the two groups that you want to map automatically. The Auto Map operation uses the settings that originate from IBM Transformation Extender, or that you set up in the Preferences window.
