CRM 2016 Dependent entities as lookup in an entity

Dependent entities (lookup)

Suppose there are dependent entities(already mentioned above), one called Disability type (PH - Physically Handicapped, VI - Visually Impaired etc) and another for Severity(Mild, Severe, with aids etc). For this, created one entity for Disability type with a text field to enter disability and created another entity Severity. Set a Parental 1:N relationship from Disability to Severity. These fields Disability and Severity are added to the Job Profile entity.

Added a lookup for Disability with the relationship as in the screenshot and a text field for Severity in the Severity entity.
