Define DDB Leaf Settings

ImportantIn this workflow example the DDB option is exposed so that the .ddb items can be imported to create the .xin file.  In some cases depending on the Federal Lands Division office, this option may be hidden.  Contact the CADD administrator for assistance or clarification if necessary.
