Smart SAP Assistant

• What is the cause and solution for SAP error message FKKINV649 - Reversing billing doc. &1 not allowed. Follow-on doc. &2 already exists. ?

  The SAP error message FKKINV649 indicates that you are trying to reverse a billing document (identified as &1) but the reversal is not allowed because a follow-on document (identified as &2) already exists. This situation typically arises in the context of billing and invoicing within the SAP Convergent Invoicing (CI) or Contract Accounts Receivable and Payable (FI-CA) modules.
  Cause:
  
  Existing Follow-On Document: The primary reason for this error is that there is a follow-on document (like a payment, credit memo, or another billing document) that has been created based on the original billing document you are trying to reverse. SAP does not allow the reversal of a billing document if there are dependent documents that rely on it.
  Document Status: The status of the billing document may also prevent reversal if it has been processed in a way that makes it non-reversible (e.g., if it has been cleared or settled).
  
  Solution:
  
  
  Check for Follow-On Documents: 
  
  Use transaction codes like FB03 (Display Document) or FBL5N (Customer Line Item Display) to check if there are any follow-on documents related to the billing document you are trying to reverse.
  Identify the follow-on document (e.g., payment, credit memo) that is preventing the reversal.
  
  
  
  Reverse or Delete Follow-On Documents: 
  
  If possible, reverse or delete the follow-on document that is causing the issue. This may involve using transaction codes like FB08 (Reverse Document) or F.80 (Clear Document).
  Ensure that you have the necessary authorizations and that reversing the follow-on document is in line with your business processes.
  
  
  
  Consult with Business Process Owners: 
  
  If the follow-on document cannot be reversed or deleted, consult with your finance or accounting team to determine the best course of action. They may suggest alternative solutions or adjustments to the billing process.
  
  
  
  Use Alternative Methods: 
  
  If the reversal is not possible due to business constraints, consider creating a new billing document to correct the situation instead of reversing the original one.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  FB03: Display Document
  FB08: Reverse Document
  FBL5N: Customer Line Item Display

  Documentation: Review SAP documentation or help files related to billing and invoicing processes in your specific SAP version.
