Lists: Does the list include a top level when it is not necessary?

When is this a problem?

When you have an unnecessary top level on a list that does not need to be summarized. Examples include a transaction list, currency list, or any other list you are using for an indicator where you do not need to see a top level or summary.

 

Why is this a problem?

When you have an unnecessary top level on a list, the engine runs calculations and recalculations that can cause a decrease in performance. This happens when summary settings are left on. Any change in a value will cause a recalculation for the summary on the top level.

 

How to correct:

Remove the parent of all from the list.
