• What is the cause and solution for SAP error message DT697 - Buffering mode is not generic; number of key fields must be 0 ?

  The SAP error message DT697, which states "Buffering mode is not generic; number of key fields must be 0," typically occurs in the context of data dictionary objects, particularly when dealing with database table buffering settings in SAP.
  Cause:
  This error arises when you attempt to set a buffering mode for a database table that is not compatible with the number of key fields defined in that table. Specifically, the error indicates that the buffering mode you are trying to use is not generic, meaning it cannot be applied to tables that have key fields. In SAP, there are different buffering modes, such as:
  
  Generic buffering: This can be used for tables with no key fields.
  Single record buffering: This is used for tables with key fields.
  
  If you try to set a buffering mode that is not appropriate for the table's structure (for example, trying to set generic buffering on a table that has key fields), you will encounter this error.
  Solution:
  To resolve this error, you need to adjust the buffering settings for the affected table. Here are the steps you can take:
  
  
  Check the Table Definition: Go to the Data Dictionary (transaction SE11) and check the definition of the table that is causing the error. Look at the key fields defined for the table.
  
  
  Adjust Buffering Settings:
  
  If the table has key fields, you should set the buffering mode to "Single record buffering" or "No buffering" instead of "Generic buffering."
  If you want to use generic buffering, you will need to remove all key fields from the table, which is generally not advisable as it may affect the integrity and functionality of the table.
  
  
  
  Activate the Changes: After making the necessary adjustments, activate the table definition to apply the changes.
  
  
  Test the Changes: After activation, test the application or process that was causing the error to ensure that the issue has been resolved.
  
  
  Related Information:
