Virtual key figure &1 depends on non-matching key figure &2

What causes this issue?

The query contains a virtual key figure, which depends on another key
figure. One of the two key figures is non-cumulative, the other is a
normal cumulative key figure. This is not permitted. Cumulative and
non-cumulative key figures are read separately from each other.
Therefore a user exit cannot combine cumulative and non-cumulative key
figures.

System Response

Query generation is aborted.

How to fix this error?

Split the virtual key figure calculation into a cumulative part and a
non-cumulative part, and combine the two parts using a normal query
formula.
