Jacopo,
I'm looking at this again, and yes I see the inconsistency between
using this versus the WorkEffortCostCalc. WorkEffortCostCalc is a
fixed cost + total number of milliseconds (setup or usage) divided by
a unit cost, whereas this is actually variable to both setup and
usage time and is denominated by hours of usage.
It does introduced an issue if we make the switch, however: how many
units will the fixed set up times in a production run be calculated
against? For example, EXAMPLE_COST has a $50 fixed setup charge and
a variable charge of $10 per minute of runtime, and the standard step
is 5 minutes, so if you run 1 unit, your standard production cost is
$100 per unit. If you run 100 units, you still have $50 of setup,
$10 * 5 * 100 = $5,000 of runtime charges, so your standard cost
becomes $5,050 / 100 = $50.50 of production costs. (Sorry if these
numbers aren't exactly right, but you get the idea...)

However the number should be correct: in fact the cost information
for fixed asset standard costing are still pulled from the
FixedAssetStdCost entity, where the following entries are stored:
<!-- Deprecated: in the future cost information will be stored in the
CostComponentCalc entity; these entries can then be associated to a
work effort thru the WorkEffortCostCalc entity. -->
<!-- This is the standard cost per hour needed to setup the fixed
asset for the task -->
<FixedAssetStdCost fixedAssetId="WORKCENTER_COST"
fixedAssetStdCostTypeId="SETUP_COST" fromDate="2005-12-31 00:01:00.0"
amountUomId="USD" amount="2"/>
<!-- This is the standard cost per hour for the usage of the fixed
asset to perform a given task -->
<FixedAssetStdCost fixedAssetId="WORKCENTER_COST"
fixedAssetStdCostTypeId="USAGE_COST" fromDate="2005-12-31 00:01:00.0"
amountUomId="USD" amount="8"/>
Since, according to the PROD_COST's routing definition, in order to
manufacture one unit of this product, the setup time for the asset is
10 minutes and the unit task time is 5 minutes, we have:
setup cost: 10 * (2 / 60) = 1/3
usage cost: 5 * (8 / 60) = 2/3
total routing cost is: 1$
