How to understand the content of "SYS"."OBJECT_DEPENDENCIES"

Hi experts,

I used "SYS"."OBJECT_DEPENDENCIES" to find out where my table in HANA is used. In the field "DEPENDENT_OBJECT_NAME" I got the entries like below: 1. package_name/view_name

2. package_name/view_name/field_name/hier.

3. package_name/view_name/hier/view_name

The 1. entry is easy to understand. what do the 2. and 3. entry mean?

Best regards,

Zhijian
