# Resolve Multiple Calculations for Crosstabs and Charts

If an intersection in a crosstab or chart contains a value that is derived from multiple calculations, you can specify the order in which to perform the calculations. The solve order must be a positive numeric value. The calculations are performed from lowest to highest solve order value.

Setting the Summary aggregation property to Calculated for a data item assigns a solve order that is higher than any other data item in a query unless a solve order is explicitly specified. If there are multiple data items that have the Summary aggregation property set to Calculated, the normal rules for solve order apply.
