Establishing a null mapping

Null mappings prevent a source property from being mapped to an Endeca property or dimension.

Most commonly, null mappings are used to prevent an automated mapping from being formed for a particular source property. In other words, you can enable automated mapping, using advanced mapping techniques, and then turn off mapping for selected source properties using null mappings.

To establish a null mapping:

  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 Null Mappings. The Null Mapping editor appears.
  5. In the Source Property text box, type the name of the source property that you want to prevent from being mapped.
  6. Click OK to close the Null Mapping dialog box.
  7. Click OK to close the Mappings dialog box.
  8. Click OK to close the Property Mapper editor.
