Define a settlement cost element for receiver type &

What causes this issue?

In allocation structure &V2& (controlling area &V3&), you did not
define which cost element should be used when settling costs/revenues
of the sender. Nor did you define receiver type &V1&.

How to fix this error?

Assign a different allocation structure to the settlement sender (->
Master data -> Settlement rule -> Goto -> Settlement parameters), or
maintain allocation structure &V2&.
