• What is the cause and solution for SAP error message FINS_RECON611 - Duplicate keys in ACDOCA: &1 message(s) ?

  The SAP error message FINS_RECON611 indicates that there are duplicate keys in the ACDOCA table, which is the Universal Journal in SAP S/4HANA. This error typically arises during the posting of financial documents or during the reconciliation process when the system detects that multiple entries with the same key (such as document number, fiscal year, and other relevant fields) already exist in the ACDOCA table.
  Cause:
  
  Duplicate Document Posting: The most common cause is that the same financial document is being posted multiple times, leading to duplicate entries.
  Data Migration Issues: If data has been migrated from another system, there may be duplicates in the data that were not cleaned up before migration.
  Custom Code or Enhancements: Custom programs or enhancements that create or modify entries in ACDOCA may inadvertently create duplicates.
  Concurrency Issues: If multiple users or processes are trying to post the same document simultaneously, it can lead to duplicates.
  
  Solution:
  
  Identify Duplicates: Use SQL queries or transaction codes (like SE16N) to check for existing entries in the ACDOCA table that match the keys of the document you are trying to post.
  SELECT * FROM ACDOCA WHERE document_number = 'your_document_number' AND fiscal_year = 'your_fiscal_year';
  
  Correct the Data: If duplicates are found, determine which entries are valid and which are not. You may need to delete or adjust the duplicate entries.
  Review Posting Logic: If the error occurs during a posting process, review the logic to ensure that documents are not being posted multiple times.
  Check Custom Code: If there are custom programs or enhancements, review them to ensure they are not causing duplicate entries.
  Implement Locking Mechanisms: If concurrency is an issue, consider implementing locking mechanisms to prevent multiple postings of the same document.
  Data Migration Cleanup: If the issue is due to data migration, perform a cleanup of the migrated data to remove duplicates before going live.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like FB03 (Display Document) to view existing documents and SE16N to access the ACDOCA table.
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide additional guidance.
  Documentation: Review SAP documentation on the Universal Journal and ACDOCA for a better understanding of how it works and how to manage entries.
