Order has no or faulty planned costs or overhead

What causes this issue?

You are attempting to do one of the following:
Calculate <DS:GLOS.work_in_process>work in process</> according to the
<LS>valuation variant for work in process and scrap</> with
<DS:GLOS.target_costs>target costs</> calculated on the basis of
planned costs
Calculate the unplanned scrap according to the <LS>valulation variant
for work in process and scrap</> using the target costs calculated on
the basis of planned costs
Split the <DS:GLOS.production_variance>production variance</> into
<DS:GLOS.variance_category>variance categories</>

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

You are attempting to calculate target costs on the basis of planned
costs for an order:
For which no <DS:GLOS.preliminary_costing>preliminary cost estimate</>
was created and therefore no <DS:GLOS.planned_costs>planned costs</>
exist or
For which no <DS:GLOS.overhead>overhead</> was calculated
Note that you can only valuate work in process and scrap at target
costs using a <DS:GLOS.product_costing>product cost estimate</> with
quantity structure. A <DS:GLOS.unit_costing>unit cost estimate</>
cannot be used to valuate work in process and scrap. This means that
you cannot use a preliminary cost estimate for a
<DS:GLOS.CO_production_order>production order without quantity
structure</> to valuate work in process and scrap.

System Response

The system cannot calculate all of the <DS:GLOS.target_costs>target
costs</> for this order for one of the following reasons:
There are no planned costs in the system.
No overhead could be calculated on the basis of target costs.
In variance calculation, the difference between actual costs and
planned costs is shown as a <DS:GLOS.remaining_variance>remaining
variance</> only.

How to fix this error?

Check the following entries in Customizing:
The assignment of the <DS:GLOS.costing_variant>costing variant</> to a
<DS:GLOS.costing_type>costing type</>
The assignment of the <DS:GLOS.valuation_variant>valuation variant</>
to a costing variant
The assignment of the <DS:GLOS.costing_sheet>costing sheet</> to a
valuation variant
