• What is the cause and solution for SAP error message FKK_EBS162 - The trunk &1 already has the maximum no. of reconciliation keys (999) ?

  The SAP error message FKK_EBS162 indicates that a specific trunk (or account) has reached the maximum number of reconciliation keys allowed, which is 999. This error typically occurs in the context of Electronic Bank Statement (EBS) processing in SAP, particularly when dealing with reconciliation of bank transactions.
  Cause:
  The error arises when the system attempts to create or assign a new reconciliation key to a trunk that has already reached its limit of 999 reconciliation keys. This can happen due to:
  
  High Volume of Transactions: If a trunk is used for a large number of transactions, it can quickly reach the maximum limit of reconciliation keys.
  Configuration Settings: The system may be configured in such a way that it generates a new reconciliation key for each transaction, leading to rapid accumulation.
  Data Management Issues: Inefficient data management practices may lead to unnecessary retention of reconciliation keys.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review and Clean Up Reconciliation Keys:
  
  Check the existing reconciliation keys for the trunk and see if any can be deleted or archived. This may involve reviewing historical transactions and determining if older keys are still needed.
  Use transaction codes like FBL1N (Vendor Line Item Display) or FBL3N (G/L Account Line Item Display) to analyze the keys.
  
  
  
  Adjust Configuration:
  
  Review the configuration settings related to reconciliation key generation. If the system is set to create a new key for every transaction, consider adjusting this to reduce the number of keys generated.
  Consult with your SAP functional consultant to see if there are any settings that can be modified to better manage reconciliation keys.
  
  
  
  Increase the Limit:
  
  If feasible, consult with your SAP Basis or technical team to see if the limit of 999 reconciliation keys can be increased. This may involve custom development or configuration changes.
  
  
  
  Implement Better Data Management Practices:
  
  Establish a regular review process for reconciliation keys to ensure that they are managed effectively and that old or unnecessary keys are removed.
  
  
  
  Consult SAP Documentation:
  
  Refer to SAP Notes or documentation related to Electronic Bank Statement processing for any specific recommendations or updates that may address this issue.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FF67 (Upload Electronic Bank Statement) and FF.5 (Manage Electronic Bank Statements).
  SAP Notes: Check for any SAP Notes related to EBS processing and reconciliation keys that may provide additional insights or solutions.
  Support: If the issue persists, consider reaching out to SAP support for assistance, especially if it is impacting business operations.
  
  By following these steps, you should be able to address the FKK_EBS162 error and manage reconciliation keys more effectively in your SAP system.
