Enter detail with the
parent-child method; this is the most prevalent method
of modeling for presentation, definition and calculation linkbases.
In this modeling technique, individual elements are organized in a tree-like structure. This
structure allows representation of information using parent-child relationships
wherein each parent can have many children, but each child has only one parent.
An example is shown below in the screen

Note β Detail should be entered only in the child table and is not required to enter details in the parent table, the total of all child members, will appear in parent table automatically.
Hope this Helps.
