• What is the cause and solution for SAP error message DT650 - Buffering parameter (BUFALLOW/KIND): &1/&2 -> &3/&4 ?

  The SAP error message DT650 relates to issues with buffering parameters in the SAP system. This message typically indicates a mismatch or inconsistency in the buffering settings for a particular database table or object. Here’s a breakdown of the components of the error message and potential solutions:
  Cause:
  
  Buffering Settings: The error message DT650 indicates that there is a discrepancy between the expected buffering parameters for a table or object. The parameters BUFALLOW and KIND represent the allowed buffering type and the current buffering type, respectively.
  Configuration Issues: This can occur if the table has been configured incorrectly in the Data Dictionary (SE11) or if there have been changes to the buffering settings that have not been properly propagated.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), there may be inconsistencies in the buffering settings.
  
  Solution:
  
  
  Check Buffering Settings:
  
  Go to transaction SE11 (Data Dictionary) and check the buffering settings for the relevant table.
  Ensure that the buffering type (e.g., Full Buffering, Single Record Buffering, No Buffering) is set correctly according to your requirements.
  
  
  
  Adjust Buffering Parameters:
  
  If the settings are incorrect, adjust them accordingly. You may need to set the buffering type to match the expected values indicated in the error message.
  Save the changes and activate the table.
  
  
  
  Consistency Check:
  
  After making changes, perform a consistency check to ensure that the changes have been applied correctly.
  You can use transaction SE14 (Database Utility) to check and adjust the database table settings.
  
  
  
  Transport Considerations:
  
  If the issue arose after a transport, ensure that the transport was successful and that all related objects were transported correctly.
  You may need to re-transport the objects or manually adjust the settings in the target system.
  
  
  
  Clear Buffer:
  
  In some cases, clearing the buffer may help resolve the issue. You can do this using transaction SM12 (for lock entries) or SM21 (for system logs) to check for any related issues.
