When is this a problem?
This is a problem when the view includes line items that aren't needed.
Why is this a problem?
The extra line items can impact performance because the view has to render the extra line items. For example, if three line items are needed, but 25 line items are defined, performance will be impacted.
How to correct:
Remove line items that aren't needed. Use Show on desired columns, instead of Hide on non-desired columns, so new line items are not added to the saved view.
