Issue
The user would like Parent-Child Entity Links enabled in their tenant.
Environment
Registry, Schemas
Cause
Enablement.
Parent-Child Entity Links are already enabled in all Industry tenants (tenants with Registry access), no changes need to be made to the tenant by Support.
Resolution steps
If Academic: Academic accounts do not have Registry access, so parent-child entity links cannot be enabled for Academic accounts. Communicate this to the user.
If Industry: Let the user know that this feature should already be enabled in their tenant and they can utilize it by going to Registry Settings --> Entity Schemas, selecting the appropriate schema, locating and editing (or creating) the appropriate schema field, and checking the 'Parent Link' box. Also note that a field cannot have both the 'Multi Select' and 'Parent Link' boxes checked.
Please see attached screenshots for more detail.
