Hi,
I would like to know the difference between top level item and parent hierarchy. Is the top level item necessary when there is parent hierarchy?. Also, when would one use Parent in the list without having Parent Hierarchy and/or top level item? Would appreciate some clear egs.
Thank you,
Cheng Hong
Add here as for my personal note.
Top Level Item = Top Level sum up locally in each list
Parent Hierarchy = Referral sum up used from other list.
Be sure to check out the new Top Level Item and Parent Hierarchy article by @greg_reynolds, which was inspired by this very discussion!
