Data Sync determines what configuration data tables to export based on the contents of the config-db.xml file found in the install_dir/database/cdt directory. If you want to include a custom configuration table that is a child of the YFS_ORGANIZATION table, you must add it to the cdt_custom.xml file. A sample of this file is located in install_dir/resources/ydkresource/cdt_custom.xml.sample. Tables in the cdt_custom.xml file are exported as part of the Configuration table group.
