• What is the cause and solution for SAP error message MC770 - Buffering only possible for database views ?

  The SAP error message MC770 ("Buffering only possible for database views") typically occurs when you are trying to set up buffering for a view that is not a database view. Buffering in SAP is a mechanism that allows frequently accessed data to be stored in memory, improving performance by reducing database access.
  Cause:
  The error arises because:
  
  Non-Database View: The view you are trying to buffer is not a database view. In SAP, only database views can be buffered. This includes views that are defined in the database and can be directly accessed by SQL.
  Incorrect Configuration: You may have attempted to enable buffering for a view that is either a projection view or a join view, which are not eligible for buffering.
  
  Solution:
  To resolve the MC770 error, you can take the following steps:
  
  
  Check the View Type:
  
  Ensure that the view you are trying to buffer is indeed a database view. You can check this in the Data Dictionary (transaction SE11) by looking at the view's properties.
  
  
  
  Change the View:
  
  If the view is not a database view, consider creating a database view that meets your requirements. You can do this by using the appropriate tables and ensuring that the view is defined correctly in the Data Dictionary.
  
  
  
  Review Buffering Settings:
  
  If you are certain that the view is a database view, double-check the buffering settings in the view definition. Make sure that the buffering option is correctly set.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more information on buffering and the types of views that can be buffered.
  
  
  
  Testing:
  
  After making the necessary changes, test the view again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Buffering Types: Understand the different types of buffering available in SAP (e.g., full buffering, single record buffering) and when to use them.
  Performance Considerations: Buffering can significantly improve performance, but it is essential to use it judiciously to avoid issues with data consistency.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
