We are working on cleaning up our costing process and one thing we have noticed is that when a shop order is created with a standard cost, and then the standard cost is changed (due to routing changes/corrections, year end cost rolls, etc.) the standard cost on the shop order can’t be updated. Then when the shop order is ran and there are actual costs, we are seeing large variances between the original standard cost and the actuals with the new standard cost. I tried the “Calculate Order Cost” button in the Shop Order Costs screen, and that seems to update the estimated cost, but not the planned standard cost. Has anyone run into this and found a way around it?

Hello Katie,

Are you talking about Shop Order Cost variance bookings? Or are you talking about the content of the tabs in Shop Order Costs page? One thing you should know here, is that when we fetch standard cost, we are retrieving the cost data from Part Cost History based on; (1) the close date of the shop order (if shop order is closed), (2) else we are using the “actual start date” of the shop order, and if the shop order is not even started (3) then we take the revised start date of the shop order. This date is then used to find the corresponding Part Cost History record.

What is the reason for this? Well, let say you want to have a close look at shop order that was closed in October 2025, then it is more to correct to compare the actual costs with the standard cost that was valid October 2025. Many many years back we always used standard cost from Part Cost, cost set 1, but a lot of customers complained and asked us to use Part Cost History values instead.

Hope this helps
