Cannot calculate target costs - itemization missing

What causes this issue?

The <DS:GLOS.Sollkosten>target costs</> are determined on the basis of
the costs calculated in a <DS:GLOS.Materialkalkulation>material cost
estimate</> (such as a current <DS:GLOS.Plankalkulation>standard cost
estimate</>) and the delivered quantity. The results of the material
cost estimate can be saved as follows:
As a <DS:GLOS.Kostenschichtung>cost component split</> (
<DS:GLOS.Kostenelement>cost components</>)
As a <DS:GLOS.Kostenartennachweis>cost element itemization</>
As an <DS:GLOS.Einzelnachweis>itemization</>
Target costs are calculated on the basis of the itemization. However, an
itemization was not saved when the standard cost estimate was created.

System Response

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

How to fix this error?

Create another material cost estimate and turn on the <LS>Itemization</>
indicator when specifying the update parameters.
<DS:TRAN.CK11N>Create material cost estimate</>
Note that you can only valuate work in process and scrap at target costs
using a <DS:GLOS.Erzeugniskalkulation>product cost estimate</> with
quantity structure. A <DS:GLOS.Einzelkalkulation>unit cost estimate</>
cannot be used to valuate work in process and scrap.
