• What is the cause and solution for SAP error message TPM0018 - Reversal as at &1 not possible, since close &2 of &3 exists ?

  The SAP error message TPM0018 indicates that a reversal operation cannot be performed because a closing entry exists for the specified period. This typically occurs in the context of Treasury and Risk Management (TRM) or Financial Accounting (FI) when trying to reverse a transaction that is already closed in the system.
  Cause:
  The error message TPM0018 is triggered when:
  
  You attempt to reverse a transaction (like a payment or a journal entry) for a period that has already been closed.
  The system has already processed a closing entry for the specified period, which prevents any further changes or reversals.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check the Closing Status:
  
  Verify the closing status of the period in question. You can do this by checking the period status in the relevant financial module (FI or TRM).
  If the period is indeed closed, you will need to determine if it is possible to reopen the period.
  
  
  
  Reopen the Period:
  
  If your business processes allow it, you may need to reopen the closed period. This typically requires specific authorizations and should be done with caution, as it can affect financial reporting.
  Consult with your finance team or SAP administrator to understand the implications of reopening a period.
  
  
  
  Post a New Transaction:
  
  If reopening the period is not feasible, consider posting a new transaction to correct the previous one instead of reversing it. This could involve creating a new entry that offsets the original transaction.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific instructions related to your version of SAP and the modules you are using.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They can provide guidance based on your specific system configuration and business processes.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FBL1N, FBL3N, or TPM1 for managing financial transactions and reversals.
  Authorization: Ensure that you have the necessary authorizations to perform reversals or to change period statuses.
  Business Processes: Understand your organization's policies regarding period closings and reversals, as these can vary significantly between companies.
  
  By following these steps, you should be able to address the TPM0018 error and proceed with your financial transactions in SAP.
