Establishing a dimension mapping

You must create a dimension before you can map it to a source property.

1. In the pipeline diagram, double-click your property mapper to open it in the Property Mapper editor.
2. In the Property Mapper editor, click Mappings. The Mappings editor appears.
3. Click New.
4. Select Dimension Mapping. The Dimension Mapping editor appears.
5. Type the name of the source property you want to map in the Source Property text box.
6. Choose the name of the dimension you want to map to from the Target Dimension menu.
7. (Optional) In the Maximum Length text box, type a value that defines the maximum source property value length allowed when creating mappings.
   Note: Source properties that have values that exceed this length are not mapped, and a warning is issued by Forge. This value overrides the default maximum length that you set on the Advanced tab of the Property Mapper editor.
8. Choose a match mode from the Match mode list.
9. Click OK to return to the Mappings editor.
10. Continue mapping source properties to dimensions.
    Note: You can map multiple source properties to a single dimension and vice versa .
