Manufactured product cost calculation method

Hi,

can someone briefly explain me, how manufactured product cost is calculated here? I did some tests after buying some components, made BOM, went through the workflow and I see that final cost (should?) be the sum of cost of all components (I am referring to output cost in Stock Entries). Now it looks like that. But if I change the cost of the receipt of one of the components, i.e. change the cost of source stock entry like add freight charges etc., final cost of already produced item is not adjusted (in Stock Entries). I did not find any tools to do that. Could someone explain me the whole idea of manuf. costing here?

Thanks.

I figured it out. Item Value Reposting seems to be doing that, but I will carry on testing.

Did you find anything?
