Rounding Differences

You may notice a slight rounding difference between the amounts on some summary and detail reports. This difference occurs because of the way that each report rounds sales data figures. The detail report sums sales by categories and then rounds the category sum. Higher level detail reports sum all categories and then round the sum. This can result in a difference of a few dollars between reports. Consider the following example:

This detail report sums all sales and purchases by category and then rounds the totals to the nearest dollar for each category.

This detail report's parent report lists the following purchases and sales for all categories for the profit center:

TOTAL

Purchases
Sales

11,819
11,046

Notice that the total sales amount differs by 1. This occurs because the detail report sums each category, rounds the total for each category, and then totals the rounded amount for all categories. For the sake of efficiency and speed, the parent report sums all categories, and then rounds the total.  This calculation method for summary reports results in a much faster report run time.
