• What is the cause and solution for SAP error message DT694 - Specify only one buffering type ?

  The SAP error message DT694 ("Specify only one buffering type") typically occurs when there is a configuration issue related to the buffering settings of a database table in the Data Dictionary (DDIC). This error indicates that multiple buffering types have been specified for a single table, which is not allowed.
  Cause:
  The error arises when:
  
  Multiple Buffering Types: You have defined more than one buffering type for a table. In SAP, a table can only have one buffering type, which can be either:
  
  No buffering
  Full buffering
  Single record buffering
  
  
  Inconsistent Configuration: There may be inconsistencies in the configuration settings for the table in the Data Dictionary.
  
  Solution:
  To resolve the DT694 error, follow these steps:
  
  
  Check Table Buffering Settings:
  
  Go to the Data Dictionary (transaction SE11).
  Enter the name of the table that is causing the error.
  Click on the "Technical Settings" button.
  Review the "Buffering" section to see what buffering type is currently set.
  
  
  
  Modify Buffering Type:
  
  If you find that multiple buffering types are specified, you need to select only one.
  Choose the appropriate buffering type based on your application needs:
  
  No Buffering: If the table is not frequently accessed.
  Full Buffering: If the entire table is frequently read.
  Single Record Buffering: If individual records are frequently accessed.
  
  
  
  
  
  Save Changes:
  
  After making the necessary changes, save the table definition.
  
  
  
  Transport Changes (if applicable):
  
  If you are working in a development environment, ensure that the changes are transported to the appropriate systems (e.g., QA, Production) as needed.
  
  
  
  Check for Related Objects:
  
  Ensure that there are no related objects (like views or indexes) that might also have conflicting buffering settings.
  
  
  
  Related Information:
  
  
  Buffering Types:
  
  No Buffering: Data is read directly from the database every time.
  Full Buffering: The entire table is loaded into the buffer, which is efficient for read-heavy tables.
  Single Record Buffering: Only individual records are buffered, which is useful for tables with a high number of unique accesses.
  
  
  
  Performance Considerations: Choosing the right buffering type can significantly impact the performance of your SAP application. It is essential to analyze the access patterns of the table to make an informed decision.
  
  
  Documentation: Refer to SAP Help documentation for more details on buffering and performance optimization.
  
  
  By following these steps, you should be able to resolve the DT694 error and ensure that your table's buffering settings are correctly configured.
