Whether using tcin_import or interactive import tool, they both will not overwrite Name and Description attribute for existing data, i.e.:
-default_name=${DB_PART_NAME} and -default_description={DB_PART_DESC} or
Solution
By default, NX will not sync Item/Item form level properties. It can be enabled via setting preference TC_NX_allow_attrsync_master_with_item=yes.
For preference TC_NX_allow_attrsync_master_with_item=no, it is designed behavior that Item.object_name (and desc) won't be updated.
For TC_NX_allow_attrsync_master_with_item=yes, Item.object_name (and desc) will get updated. This should happen with overwrite on exiting item in interactive import as well as tcin_import.
