What causes this issue?

Document with document number (BELNR) &V1& was generated in the entry
view. In this way, you can use the number of the entry view document to
look for documents in the document display screen.
You find the number of the entry view document in tables BKPF and BSEG
or BSEG_ADD and in the line item table for General Ledger Accounting in
field BELNR.
Company code: &V2&
Ledger: &V3&
The document number of the accounting document is &V4&. You find this
document number in table BKPF in field AWKEY, in the line item table of
General Ledger Accounting in field REFDOCNR, and in the control table of
allocation T811D in field DOCNR or RDOC.
For the leading ledger, the document number of the entry view document
is always the document number of the accounting document. For a
non-leading ledger, you specify in Customizing whether the document
numbers of the accounting documents always correspond to the document
numbers of the entry view documents or whether you want to enter your
own numbers for the accounting documents.
