Hi, experts!
In APEX 20.1,
I tried to use Create Page Wizard to create a page of master detail side by side form that is based on the table of E_TASK(master table) and E_PROCESS(detail table).
And I have created the FK constraints for this two tables.
But when I tried the Create Page Wizard I cannot find the detail table shown as the below image. And cannot Create this page in the end.

What had I missied?
Thanks for any suggetsions in advance.
