• What is the cause and solution for SAP error message FINS_RECON837 - COSS_BAK differs from COSS in values: &1 message(s) ?

  The SAP error message FINS_RECON837 indicates a discrepancy between the values in the COSS (Cost Object Controlling) table and the COSS_BAK (Backup of COSS) table. This typically occurs during the reconciliation process in the Controlling (CO) module, particularly when there are inconsistencies in the cost object data.
  Cause:
  
  
  Data Inconsistency: The primary cause of this error is that the values in the COSS table do not match the corresponding values in the COSS_BAK table. This can happen due to various reasons, such as:
  
  Manual adjustments or corrections made to cost objects that were not reflected in the backup table.
  Issues during data migration or system upgrades that led to discrepancies.
  Errors during posting or processing of cost allocations.
  
  
  
  Incomplete or Failed Processes: If a process that updates these tables was interrupted or failed, it could lead to inconsistencies.
  
  
  Custom Developments: If there are custom programs or enhancements that manipulate cost object data, they might not be correctly updating both tables.
  
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Analyze the Discrepancy:
  
  Use transaction codes like KSB1 (Cost Centers: Actual Line Items) or COSS (Cost Object: Actual Line Items) to review the entries in both tables.
  Identify the specific message(s) indicated by the error message (the &1 part) to understand which values are differing.
  
  
  
  Reconcile the Data:
  
  If the discrepancies are due to manual adjustments, ensure that all changes are consistently applied to both tables.

  Use SAP Standard Reports:
  
  Utilize standard SAP reports for reconciliation in the CO module to identify and correct discrepancies.
  
  
  
  Check for Custom Code:
  
  If there are custom developments, review the code to ensure it correctly updates both COSS and COSS_BAK tables.
  
  
  
  Consult SAP Notes:
