Standard cost vs. actual cost

Hi all,
I have a query regarding how the ERPnext is going to post cost vairones after calculating the actual operational cost against the standard cost. I know the system is going to display both information but I want to know where the posting happening in the closing of each work order.
and if I want to do the closing for monthly or yearly is there any kind of clear steps I need to follow so the system is going to take all the operational expenses that in the BOM and post them in the cost centers with the distribution cycle of the finance of any expense that not related to manufacturing?

thanks in advance

Can you explain with an example? Which standard cost are you referring to?

As checked internally, ERPNext has a feature to update FG item’s valuation if you update the landed cost voucher for the raw material. This was done in one of the latest updates.
