• What is the cause and solution for SAP error message PU826 - Log is too big (& bytes); messages displayed up to level 3 only ?

  The SAP error message PU826 indicates that the log file for a particular process has exceeded the maximum size limit, which is causing the system to restrict the amount of log information displayed. This can happen during various operations, such as batch jobs, data uploads, or other processes that generate extensive logs.
  Cause:
  
  Excessive Logging: The process is generating too many log entries, which can occur due to a large volume of data being processed or detailed logging settings.
  Configuration Settings: The logging level may be set too high, leading to more detailed logs than necessary.
  Insufficient Log Management: Logs may not be managed properly, leading to accumulation and exceeding size limits.
  
  Solution:
  
  
  Adjust Logging Level:
  
  Review the logging settings for the process. If the logging level is set to a high verbosity (e.g., level 4 or higher), consider lowering it to level 3 or lower to reduce the amount of log data generated.
  This can typically be done in the transaction or program settings where the logging level is defined.
  
  
  
  Log Management:
  
  Regularly monitor and manage log files to prevent them from growing too large. Implement a log rotation or archiving strategy to keep log sizes manageable.
  You can use transaction codes like SLG1 (Application Log) to review and delete old logs if necessary.
  
  
  
  Increase Log Size Limit:
  
  If necessary, you can increase the maximum log size limit in the system configuration. This may require adjustments in the system parameters, which should be done with caution and typically involves consulting with your SAP Basis team.
  
  
  
  Review Process:
  
  Analyze the process that is generating the logs. If it is processing a large volume of data, consider optimizing the process to reduce the amount of logging or breaking it into smaller batches.
  
  
  
  Check for Errors:
  
  Investigate if there are any underlying issues causing excessive logging, such as repeated errors or warnings that are being logged.
  
  
  
  Related Information:
  
  Transaction Codes: 
  
  SLG1: To view application logs.
  SM37: To monitor background jobs and their logs.
  
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to logging issues.
  Documentation: Review SAP documentation for best practices on log management and performance tuning.
  
  By addressing the logging level and managing log files effectively, you can mitigate the PU826 error and ensure smoother operation of your SAP system.
