• What is the cause and solution for SAP error message IST_EBS162 - The trunk &1 already has the maximum no. of reconciliation keys (999) ?

  The SAP error message IST_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, where reconciliation keys are used to match bank transactions with the corresponding entries in the SAP system.
  Cause:
  
  Maximum Limit Reached: The trunk/account has already accumulated 999 reconciliation keys, which is the maximum limit set by the system.
  Frequent Transactions: If there are a high volume of transactions being processed for that trunk, it can quickly reach the limit.
  Configuration Settings: The system may be configured to allow only a certain number of reconciliation keys for each trunk.
  
  Solution:
  
  
  Review and Clean Up: 
  
  Check the existing reconciliation keys for the trunk and see if any can be deleted or archived. This may involve reviewing old or unnecessary transactions that are no longer needed.
  If the reconciliation keys are no longer relevant, you can delete them to free up space for new ones.
  
  
  
  Increase the Limit: 
  
  If your business processes require more than 999 reconciliation keys, consider discussing with your SAP administrator or technical team about increasing the limit, if possible. This may involve changes in configuration settings or custom development.
  
  
  
  Split Transactions: 
  
  If feasible, consider splitting transactions across multiple trunks/accounts to distribute the load and avoid hitting the limit on a single trunk.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or consult with SAP support for specific guidance on managing reconciliation keys and any potential configuration changes that can be made.
  
  
  
  Regular Maintenance: 
  
  Implement a regular maintenance schedule to review and manage reconciliation keys to prevent reaching the limit in the future.
