Difficulty in dot-walking parent fields on form layout

[Dee S]

I've a table in which there is one field called 'Parent' which is reference to Task table. 'Parent' field holds Case Number.

Requirement is to get all Case details on the form. I thought I can achieve this by dot-walking through Parent field but all I can see are Task fields not Case fields as Reference is Task.

But when I tried to configure List Layout it is possible to get Case Details.

Please help me to get Case Details on form.

Update:

Case table parent is 'Task' that is why dot-walking is not showing Case fields. Hence new field has been created for Case.

Is this requried to create a new field on that table? can't we take the pareant fields on the form layout editor?

is this the only way?
