• What is the cause and solution for SAP error message USMD1B063 - Buffering not allowed, log switched off ?

  The SAP error message USMD1B063: Buffering not allowed, log switched off typically occurs in the context of SAP Master Data Governance (MDG) when there is an attempt to buffer data that is not allowed due to certain settings or configurations. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Buffering Settings: The error indicates that the buffering for the specific table or data object is not allowed. This can happen if the table is configured in such a way that it does not support buffering.
  Log Settings: The log for the data operation may be switched off, which means that changes to the data cannot be tracked or buffered.
  Data Model Configuration: The data model in MDG may have specific configurations that prevent buffering for certain entities or attributes.
  
  Solution:
  
  
  Check Buffering Settings:
  
  Review the buffering settings for the relevant database tables. You can do this by checking the table definition in the Data Dictionary (transaction SE11).
  Ensure that the buffering is enabled if it is required for your use case. If buffering is not needed, you may need to adjust your data handling approach.
  
  
  
  Log Configuration:
  
  Verify the logging settings for the relevant data model. In MDG, you can check the configuration settings in the MDG customizing transaction (e.g., transaction MDGIMG).
  Ensure that the logging is enabled for the relevant data operations. If logging is switched off, you may need to enable it to allow for proper data handling.
  
  
  
  Review Data Model:
  
  Check the data model configuration in MDG to ensure that the entities and attributes are set up correctly. This includes reviewing the settings for the specific data model you are working with.
  If necessary, consult with your MDG configuration team to ensure that the data model aligns with your business requirements.
  
  
  
  Consult SAP Notes:
  
  Look for any relevant SAP Notes that may address this specific error. SAP frequently updates its knowledge base with solutions and workarounds for known issues.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error no longer occurs and that the data operations are functioning as expected.
