• Message number: 351

• Message text: Do not create line IDs of 'Spec. costs' cat. when defining assignmt rules

What causes this issue?

If actual costs of <DS:DE.KATEGORIE>category</> <ZH>D</> are incurred,
the system debits the <GL:cost_of_sales>cost of sales</> directly.
<DS:GLOS.line_ID>Line IDs</> of category <ZH>D</> are not allowed for
results analysis objects with a <DS:GLOS.results_analysis_key>results
analysis key</> of <DS:GLOS.results_analysis_type>results analysis type
</> <ZH>F</>, <ZH>S</>, or <ZH>B</>.

How to fix this error?

Go into Customizing and assign the line IDs of category <ZH>D</> to a
different category.
There is no cost of sales with results analysis types <ZH>F</> and
<ZH>S</>. You can select category <ZH>K</> instead, for example.
With results analysis type <ZH>B</> it is recommended that you use
results analysis with dynamic items instead of category <ZH>K</>, and
that you select the apportionment reason "Costs never to be billed" in
Customizing for dynamic items. This allows the costs to flow directly
into the cost of sales.
