Changing Mapping Information for a Dimension

To change the mapping information for the dimensions in a data map:

1. View the Data Maps listing page.
   See Viewing Data Maps.
2. Click an existing data map.
3. Select a dimension under Source, and then click to select a new source dimension or Smart List to use for the mapping.

   If all dimensions are mapped, you can only map an existing source dimension to a Smart List (only "Smart List" is displayed when you click). To unmap a dimension so that it can be mapped to another dimension, select the dimension under Source, and then click . The dimension is moved to Unmapped Dimensions.

4. Optional: If needed, exclude source members from the data map.
   For more information, see Excluding Source Members from a Data Map.
5. Select a dimension under Target, and then click to select a member for mappings.
   For most data maps the target selection does not need any changes.
6. Optional: If there are more members and the requirement is to restrict the members in the Target Selection from member mapping, then modify the Target Selection.
   For more information, see Clearing and Restricting Target Selections for Mappings.
