How to reproduce:

1. Create a parent object type and set it to Pass all attributes to child object types
2. Create a child object type for the parent recently created
3. Add a few unique attributes for the child object type
4. Create a CSV import with the following structure:

   | PARENT_ATTR_1  | PARENT_ATTR_2  | PARENT_ATTR_3  | CHILD_ATTR_1  | CHILD_ATTR_2  |
   |----------------|----------------|----------------|---------------|---------------|
   | Parent_value_1 | Parent_value_2 | Parent_value_3 | Child_value_1 | Child_value_2 |

1. Finish the import configuration by adding the Parent and Child Object type mapping
2. Import the data

Expected results:

• child object mapping to import the child attributes data

Actual results:

• child attributes data are not imported

Workaround:

Currently there is no workaround for this issue.  Should one become available this section will be updated.
