SAP Message AJ667 - Document &1 -> print document &2 not reversed (chain &3)

Diagnosis
Billing document &V1& belongs to print document &V2& that has not beenreversed.
You want to remove the billing document &V3& from a billing order intransaction EA24.
However, &V3& is the end of a chain of multiple adjustment reversals,to which at least &V1& still belongs.
You cannot execute transaction EA24 unless all print documents in thechain have been reversed. Otherwise the rebilling of the billing orderno longer takes the difference bills of the chain into account, whichcan lead to incorrect billing.
