If there are any saved views, do they use the correct filtering?
When is this a problem?
This is a problem when saved views use multiple filters per tab.
Why is this a problem?
Multiple filters on a tab can cause performance issues. The data is read for the first filter, then those results are read for the next filter, etc.
How to correct:
Filters should be set up using Boolean values and have only one line item filtering each dimension. If you need to, consolidate filtering line items into one line item. Be sure to use the Notes section to identify that this line item is used in a filter.
