3102562 - Target cost calculation for activity confirmation on production order

You want to know how the target cost being calculated for activity confirmation on production order.

SAP S/4HANA Cloud

Target costs of manufacturing orders are calculated according to different source of plan costs adjusted to the actual output quantity at the time of goods receipt as following:
Lot-size-dependent costs: Costs vary with the lot size are divided by the costing lot size (and plan output quantity), then multiplied by the actual quantity delivered (the yield).
Lot-size-independent costs: Costs do not vary with the lot size (such as setup costs) are used directly as target costs.

For example:
You create a material cost estimate, under 'Quantity Structure' view, here you can find the related routing information.
Double click the routing number, you will jump to the routing master data,
Routing has 2 operations, operation 0010 and 0020.
Each operation assigns a work center, operation 0010 -> work center A, operation 0020 -> work center B. 

Double click the work center A/B, you will jump to the work center master data.
Click the 'Costing' tab, you can find the related formula of each work center, 
Work Center A, Formula A = Labor.
Work Center B, Formula B = Labor * Operation quantity / Base quantity.

Which means Formula A is lot size independent, Formula B is lot size dependent.
So how the target cost being calculated?

For material cost estimate, costing lot size is M.
Activity/work center A consumes h1 hour, cost is C1.
Activity/work center B consumes h2 hour, cost is C2.

Production order has actual quantity and plan quantity. 
Total Target quantity  = h1 + h2/M*actual quantity.
Total Target cost = C1 +C2/M*actual quantity.

If there's no lot size independent formula(like above example Formula A),
the target quantity = consumed hours/costing lot size * order actual output quantity.
