• What is the cause and solution for SAP error message DD_MT_SHARING109 - Table buffer invalidation deferred to Step 8 due to container switch ?

  The SAP error message DD_MT_SHARING109 indicates that there is an issue with the table buffer invalidation process, which has been deferred due to a container switch. This typically occurs in the context of database operations where the system is trying to manage the buffer for a table that is being accessed or modified.
  Cause:
  
  Container Switch: This error usually arises when there is a switch between different database containers (e.g., when using multiple database schemas or instances). The system cannot immediately invalidate the table buffer because it is in the process of switching contexts.
  Buffer Management: The table buffer is used to cache data for performance reasons. If the data in the buffer is no longer valid (due to changes in the database), the system needs to invalidate it. However, if a container switch is happening, this invalidation cannot be processed immediately.
  Concurrency Issues: If multiple transactions are trying to access or modify the same data simultaneously, it can lead to deferred invalidation.
  
  Solution:
  
  Wait for the Process to Complete: Often, this message is temporary. If the system is busy with other operations, waiting for those to complete may resolve the issue.
  Check for Long-Running Transactions: Investigate if there are any long-running transactions that might be causing the delay. You can use transaction codes like SM50 or SM66 to monitor active processes.
  Review Buffer Settings: Check the buffer settings in the SAP system. You may need to adjust the parameters related to table buffering in transaction RZ10 or RZ11.
  Database Administration: If the issue persists, it may require intervention from a database administrator to check for any underlying issues with the database or the configuration of the database containers.
  SAP Notes: Look for relevant SAP Notes that might address this specific error. SAP frequently updates its knowledge base with solutions for known issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE14 (Database Utility), and SM12 (Lock Entries) for further investigation.
  SAP Support: If the issue continues and impacts system performance, consider reaching out to SAP Support for assistance.
  Documentation: Review SAP documentation related to table buffering and database performance tuning for best practices.
  
  In summary, the DD_MT_SHARING109 error is related to the management of table buffers during a container switch, and while it may resolve itself, monitoring and adjustments may be necessary to prevent future occurrences.
