Invalid document reference &1 &2 &3 for cross-company-code transaction.

What causes this issue?

In the case of postings using the reference transaction &V1&, the
document number of the FI document is derived from the reference key of
the posting.
. When a cross-company-code transaction is posted, the reference key
must be built on the basis of the leading company code.
.
.
However, the company code specified in organizational unit &V3& is not
the leading company code of this transaction.
. Consequently, document number &V2& cannot be applied for the document
of the leading company code.
.
.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
