• What is the cause and solution for SAP error message CFD_RUNTIME062 - Buffer was invalidated in a concurrent session. ?

  The SAP error message CFD_RUNTIME062: Buffer was invalidated in a concurrent session typically occurs in the context of SAP's Collaborative Forecasting or similar applications where multiple users or processes are accessing the same data concurrently. This error indicates that the data buffer being accessed has been invalidated due to changes made in another session, leading to potential inconsistencies or conflicts.
  Cause:
  
  Concurrent Access: The most common cause is that multiple users or processes are trying to access or modify the same data simultaneously. When one session updates the data, it invalidates the buffer for other sessions that are still trying to use the old data.
  Session Timeout: If a session has been inactive for a while, it may time out, leading to invalidation of the buffer when a user tries to access it again.
  Data Locking: SAP uses locking mechanisms to prevent data inconsistencies. If a session locks a record and another session tries to access it, the buffer may be invalidated.
  
  Solution:
  
  Refresh the Data: The simplest solution is to refresh the data in your session. This can often be done by reloading the screen or navigating away and back to the relevant transaction.
  Avoid Concurrent Modifications: If possible, coordinate with other users to avoid simultaneous modifications to the same data. This can help prevent buffer invalidation.
  Check for Long-Running Transactions: If you have long-running transactions, consider breaking them down into smaller parts to reduce the likelihood of buffer invalidation.
  Session Management: Ensure that sessions are properly managed and closed when not in use. This can help reduce the number of concurrent accesses to the same data.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this issue. There may be specific fixes or recommendations based on the version of SAP you are using.
