The Item Summary tab on the Job Cost report has been repurposed. Previously, it showed the sum of all job values related to that item, which was not a frequently used metric. We’ve updated the system so that it now shows the average unit cost information for each item instead.
This helps you understand, in the time frame selected, what you are estimating it will cost to make an item vs what it is actually costing you, and what is driving that variance (which could be labor, material, outside processing, machine costs, etc). The default summary shows the item rollup and the job breakout so that you can see if any particular job is skewing the data.
