At least one field in this PivotTable has Top 10 AutoShow applied. Top 10 filtering has been improved in Microsoft Excel so that the items included in a Top 10 filter are now selected by dynamically evaluating their values in the context of where the field is placed in the PivotTable. This improvement might result in a different filtered list of items after the PivotTable is refreshed or, if the data source (cube) does not contain the neccessary totals, the Top 10 filter will be removed. Click OK to refresh.
