- Export to Shapefile "Error: Duplicate property name: .."

During a SHP export of a feature an error appears "Error: Duplicate Property Name: <property name>", and no features are exported.
The DBF file generated when exporting to Esri shapefile has a 10 character limit for property names. Therefore, if you have two properties named LOWER_LEFT_NODE and LOWER_LEFT_LEAD, the export utility will truncate the first property to LOWER_LEFT and generate a 'duplicate property name' error on the second. 

To overcome this, remap the property names prior to exporting with the following  steps.

• In the Map Import/Export dialog, select a feature, right click > Export > Show Properties > Ungrouped.
  
• A "+" is added in front of the selected feature.
  Expand the selected feature with the "+". The properties are listed.
• Select a property that needs to be remapped.
  A section Property Parameters is now available.
• In the field Mapped Name, enter a new name.
  
  
  
• Run the SHP export again.
