How To Fix G4016 - There is no JV doc. line & in company &, but an FI doc. line

G4016 - Overview

• Message type: E = Error

• Message class: G4 - EC-CS Consolidation

• Message number: 016

• Message text: There is no JV doc. line & in company &, but an FI doc. line

What causes this issue?

There is an FI-document line &v1& without a related JV-document line.
This should not happen. At least one JVA document line should exist
for each FI document line. Missing JV-document lines are the result of
incorrect handling in the JV-IM.
Since the document is inconsistent, no posting is possible.

How to fix this error?

Please create an OSS message (ISOIL/UPSTREAM - ISOUS) with a
description of the document (transaction, involved lines like discount,
taxes ...) and if it happens in clearing, a list of the items you
selected for clearance, and allow SAP access to your system. Please add
the following information to the OSS message: IP-address, instance nr.,
client, user with the authority for that transaction, password, company
code.

G4016 - Details

• The SAP error message G4016 indicates that there is a discrepancy between the journal voucher (JV) document lines and the financial accounting (FI) document lines in a specific company code. This error typically arises during the posting of transactions that involve both FI and controlling (CO) documents, particularly when there is an expectation of a JV document line that does not exist.
  
  Cause:
  
  Missing JV Document Line: The error occurs when the system expects a JV document line for a specific transaction but cannot find one. This can happen if the JV document was not created or was deleted.
  Inconsistent Document Types: The document types used in the transaction may not be compatible or correctly configured to allow for the creation of both FI and JV lines.
  
  Configuration Issues: There may be issues in the configuration of the integration between FI and CO modules, leading to inconsistencies in document postings.
  Data Entry Errors: Incorrect data
