You are possibly settling revenues to an object without revenues

What causes this issue?

You settle a sender with revenues (sales order or internal order that
can carry revenues, or a billing element) to receiver &V1&, which does
<ZH>not</> carry revenues.
The sender with revenues has debits under cost element &V2& (business
transaction: &V3&). It is not possible to tell whether the debits are
costs or revenues. Therefore, revenues may be settled to receiver &V1&,
which does <ZH>not</> have revenues.
This could be due to the following:
<ZK>Sender 1</> (settlement with settlement cost element) --<ZH>></>
<ZK>Sender 2</> --<ZH>></> <ZK>Receiver</>
Once settlement from <ZK>Sender 1 </>to<ZK> Sender 2 </> is complete,
you <ZH>cannot</> tell whether costs or revenues were posted to
<ZK>sender 1</>. This information is only kept if you settle <ZK>sender
1</> to <ZK>sender 2</> by cost element.
