Parent hierarchy & Top level
Hello fellow Anaplanners,
I have a query, I was going through an existing model and where I saw there are multiple composite hierarchy built having just 2 lists. i.e one is parent list (say 'X') and another is child list (say 'Y').
Now here in first list 'X' (which is parent for the other) there is only 1 member 'All X members'.
The second list 'Y' is configured to have List 'X' as its parent. this list have 10 members.
Now, I saw they have created 'Top Level' (say 'all items') for this list 'Y' .
so, here List 'Y' has both a Parent hierarchy and Top level.
I am unable to understand what was the logic behind same, as both parent hierarchy and top level are achieving the same purpose.
My question in this case are as follows:
1. is there any benefits of having both Parent hierarchy and Top level in a child list?
2. say if the parent list is just require to have 1 member, as here we have the case, does it require to be built as a composite list? they could have just create it as a flat list having a top level.
3. which is best option here, to have parent list or just to have top level. if we are going to look it performance wise?
Thanks in advance!!
