You can dynamically change the layout of a PivotTable form to analyze data in different ways. You can rearrange row headings, column headings, and page fields until you achieve the desired layout. Each time you change the layout, the PivotTable form immediately recalculates the data based on the new arrangement. In addition, as source data changes, you can update the PivotTable form.
A PivotTable form performs the calculations you choose, such as sums (the default for numeric fields) and counts (the default for text fields), based on how the data is arranged in the PivotTable form. For example, a PivotTable form can display a field's values horizontally or vertically, and then calculate the total of the row or column.
A PivotTable form can also use a field's values as row or column headings, calculating individual amounts at the intersection of each row and column heading, and then calculating subtotals and grand totals. For example, to analyze sales by product category for each employee, you can list employee names as column headings across the top of the PivotTable form, product categories as row headings down the side of the PivotTable form, and the sales amount calculated by product category for each employee at the intersection of each row and column.
You can limit the records that the PivotTable form uses by designating a field as a page field
Each time you open a PivotTable form, the PivotTable form shows you the data that was current the last time you activated the PivotTable form. To display the most current data in the PivotTable form, you need to update the data.
