• What is the cause and solution for SAP error message FINS_RECON520 - CoCd &1: Check BSEG vs. ACDOCA started at &2 and ended at &3 ?

  The SAP error message FINS_RECON520 indicates a reconciliation issue between the line items in the BSEG table (which contains accounting document line items) and the ACDOCA table (which contains the Universal Journal entries in S/4HANA). This error typically arises during the reconciliation process when there are discrepancies between these two tables for a specific company code (CoCd).
  Cause:
  
  Data Migration Issues: If data was migrated from an older SAP system to S/4HANA, inconsistencies may arise if the migration was not executed properly.
  Manual Adjustments: Manual postings or adjustments that were made directly in BSEG without corresponding entries in ACDOCA can lead to mismatches.
  Configuration Errors: Incorrect configuration settings in the system can lead to discrepancies between the two tables.
  Document Deletion: If documents were deleted or reversed in one table but not in the other, this can cause reconciliation issues.
  Parallel Accounting: If there are different accounting principles being applied (e.g., IFRS vs. local GAAP), this can lead to differences in the entries.
  
  Solution:
  
  Run Reconciliation Report: Use the transaction code FINS_RECON to run the reconciliation report. This report will help identify the discrepancies between BSEG and ACDOCA.
  Analyze the Discrepancies: Review the detailed report generated to understand the nature of the discrepancies. Look for missing entries, incorrect postings, or any other anomalies.
  Correct Data: Based on the analysis, make the necessary corrections. This may involve:
  
  Posting missing entries in ACDOCA.
  Adjusting or reversing incorrect entries.
  Ensuring that all manual adjustments are reflected in both tables.
  
  
  Check Configuration: Review the configuration settings related to financial accounting to ensure they are set up correctly.
  Consult SAP Notes: Check for any relevant SAP Notes that may address known issues or provide guidance on resolving reconciliation problems.
  Engage SAP Support: If the issue persists and cannot be resolved internally, consider reaching out to SAP support for assistance.
  
  Related Information:
  
  BSEG Table: Contains line items for accounting documents in classic SAP systems.
  ACDOCA Table: Part of the Universal Journal in S/4HANA, which consolidates various financial data into a single table.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FINS_RECON for reconciliation and FB03 for viewing document details.
  Documentation: Review SAP documentation and guides related to financial accounting and reconciliation processes in S/4HANA.
