Level for cost overrun does not correspond to valuation level

What causes this issue?

One of the following situations has occurred:
Through the valuation level you specified that you want to valuate at
totals level (per order or project). However, you selected a method for
dealing with the plan overrun (actual costs exceeding planned costs)
that replaces the planned values with the actual values for each
<DS:GLOS.line_ID>line ID</>. This combination is not possible.
Through the valuation level you specified that you want to valuate each
line ID separately. However, you selected a method for dealing with the
plan overrun (actual costs exceeding planned costs) that replaces the
planned values with the actual values at totals level. This combination
is not possible.
