• What is the cause and solution for SAP error message SBUF012 - Object(s) of buffer instance '&1' invalidated ?

  The SAP error message SBUF012 indicates that one or more objects in a buffer instance have been invalidated. This typically occurs in the context of SAP's buffer management system, which is responsible for caching data to improve performance. When an object is invalidated, it means that the data in the buffer is no longer valid, often due to changes in the underlying database or application logic.
  Cause:
  
  Database Changes: If the underlying data in the database has changed (e.g., updates, deletions), the buffer instance may invalidate the cached objects to ensure that the application does not use stale data.
  Transport Requests: If a transport request is imported that changes the structure or data of the objects in the buffer, it can lead to invalidation.
  Configuration Changes: Changes in configuration settings or application logic that affect how data is retrieved or stored can also cause invalidation.
  System Updates: Upgrades or patches to the SAP system can lead to changes that invalidate existing buffer entries.
  
  Solution:
  
  Refresh the Buffer: The simplest solution is to refresh the buffer. This can often be done by using transaction codes like SM12 (to delete lock entries) or SM21 (to check system logs) to identify issues. You may also use SICF to refresh the buffer for specific services.
  Check for Transport Requests: If the issue arose after a transport, check the transport logs and ensure that all necessary objects were transported correctly.
  Rebuild the Buffer: In some cases, you may need to rebuild the buffer. This can be done through transaction SBD1 (for buffer management) or by using specific programs designed to clear and rebuild buffers.
  Monitor Changes: Keep track of changes made to the system, including database updates, configuration changes, and transport requests, to identify potential causes of invalidation.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or updates regarding this error message. There may be specific patches or recommendations provided by SAP.
  
  Related Information:
