Mat. &1 in plant &2: itemization does not match cost component split

What causes this issue?

The total value of the itemization for material &V1& in plant &V2&
differs from the total value of the cost component split. This is always
possible if:
A material component with a different result is costed again and saved
You are using primary cost component splits for activity types/processes
and you carry out a new price calculation for the corresponding period
after costing, which results in new prices and therefore new primary
cost components splits, and you have specified that the primary cost
component split is the main cost component split in the cost estimate

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

System Response

The system behavior in this case is correct and cannot be changed. The
reason is that the itemization of a cost estimate for the cost component
view just selected must be generated dynamically when it is displayed.
That is, the cost component splits of the itemization items must be
read.
Depending on the view (cost of goods sold, sales and administration
costs, etc.), the total value of the itemization may no longer match the
total value of the cost component split.

How to fix this error?

To avoid such problems in the future, you should do the following:
If a material component with changed values was costed, always cost the
header material again.
Cost all materials again after price calculation is run for a particular
period.
