Smart SAP Assistant

• What is the cause and solution for SAP error message SBUF021 - Table "&1" is not buffered ?

  The SAP error message SBUF021 indicates that a specific table (denoted by "&1") is not buffered. This message typically arises when you attempt to access or perform operations on a table that is not set up for buffering in the SAP system.
  Cause:
  
  Table Configuration: The table in question is not configured for buffering in the Data Dictionary (SE11). This means that the system will not cache the data in memory, which can lead to performance issues when accessing the table frequently.
  Access Method: The operation you are trying to perform may require buffered access, but the table is not set up for it.
  Performance Considerations: Some tables are intentionally left unbuffered due to their nature (e.g., frequently changing data) to ensure that users always access the most current data.
  
  Solution:
  
  
  Check Table Buffering Settings:
  
  Go to transaction SE11 (Data Dictionary).
  Enter the name of the table that is causing the error and click on "Display".
  Check the buffering settings in the "Technical Settings" section.
  If appropriate, you can change the buffering settings to "Buffering Active" or "Buffering Read" based on your requirements.
  
  
  
  Consider the Impact:
  
  Before enabling buffering, consider the implications on performance and data consistency. Buffering is beneficial for read-heavy tables but can lead to stale data if the table is frequently updated.
  
  
  
  Consult with Basis Team:
  
  If you are unsure about changing the buffering settings, consult with your SAP Basis team or a functional consultant. They can provide insights into whether buffering is suitable for the specific table based on its usage.
  
  
  
  Alternative Solutions:
  
  If buffering is not suitable for the table, consider optimizing your queries or access methods to reduce the performance impact of accessing unbuffered tables.
  
  
  
  Related Information:
  
  Buffering Types: SAP supports different types of buffering, such as full buffering, single record buffering, and no buffering. Understanding these types can help you make informed decisions about which tables to buffer.
  Performance Monitoring: Use transaction ST02 (Tune Summary) to monitor buffer performance and identify any potential issues related to buffering in your SAP system.
  Documentation: Refer to SAP Help documentation for more details on table buffering and best practices for performance optimization.
  
  By following these steps, you should be able to address the SBUF021 error and improve the performance of your SAP system as needed.
