• What is the cause and solution for SAP error message DT759 - Buffered view &: Runtime object of basis table & was modified ?

  The SAP error message DT759 indicates that a buffered view has encountered a runtime object of a basis table that has been modified. This typically occurs in the context of SAP's database buffering mechanism, which is designed to improve performance by caching frequently accessed data in memory. However, if the underlying data in the database changes, the buffered view may become inconsistent, leading to this error.
  Cause:
  
  Data Modification: The most common cause of this error is that the underlying table data has been modified (inserted, updated, or deleted) while the buffered view is still in use.
  Buffer Invalidation: If the buffer for the table is invalidated (for example, due to a change in the data), the buffered view may not reflect the current state of the database.
  Configuration Issues: There may be issues with the configuration of the buffering settings for the table in question.
  
  Solution:
  
  
  Refresh the Buffer: You can refresh the buffer for the affected table. This can be done by:
  
  Using transaction code SM12 to check for any locks that might be causing issues.
  Using transaction code SM04 to see if any users are holding onto the buffered view.
  If necessary, you can clear the buffer using transaction SNOTE or by restarting the application server.
  
  
  
  Check Table Buffering Settings: 
  
  Go to transaction SE11 (Data Dictionary) and check the buffering settings for the table in question. Ensure that the buffering is set correctly based on your business requirements.
  If the table is not frequently updated, consider using full buffering. If it is frequently updated, you may want to use no buffering or single record buffering.
  
  
  
  Review Code: If you are developing custom code that accesses the buffered view, ensure that it handles data changes appropriately. Consider implementing logic to refresh or re-fetch data when necessary.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  System Restart: In some cases, a system restart may be necessary to clear any lingering issues with the buffer.
  
  
  Related Information:
  
  Buffering Types: Understand the different types of buffering in SAP (full buffering, single record buffering, and no buffering) and how they affect performance and data consistency.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11, SM12, SM04, and SNOTE for managing database objects and buffers.
  SAP Documentation: Refer to SAP's official documentation for more detailed information on buffering and performance optimization.
  
  If the issue persists after trying the above solutions, it may be beneficial to engage with SAP support for further assistance.
