• What is the cause and solution for SAP error message CNV_MBT_ULV001 - Logging of message &2(&1) type &3 suppressed (limit of &4 msgs. reached) ?

  The SAP error message CNV_MBT_ULV001 indicates that the logging of messages has been suppressed because a predefined limit of messages has been reached. This message is typically related to the SAP Conversion and Migration tools, particularly in the context of data migration or transformation processes.
  Cause:
  The error occurs when the number of messages logged during a migration or conversion process exceeds a specified limit. This limit is set to prevent excessive logging, which can lead to performance issues or overwhelming amounts of log data that are difficult to manage.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Increase the Logging Limit:
  
  You can adjust the logging limit in the relevant configuration settings. This may involve changing parameters in the migration tool or adjusting settings in the SAP system to allow for more messages to be logged.
  
  
  
  Review and Clean Up Logs:
  
  If the logs are not being monitored or cleaned up regularly, consider reviewing the existing logs and deleting unnecessary entries. This can help free up space and allow for new messages to be logged.
  
  
  
  Analyze the Logged Messages:
  
  Investigate the messages that have already been logged to identify any recurring issues or errors that may need to be addressed. This can help reduce the number of messages generated in the future.
  
  
  
  Adjust Logging Levels:
  
  Depending on the context, you may want to adjust the logging level to reduce the verbosity of the messages being logged. This can help manage the number of messages without losing important information.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or notes related to the specific migration or conversion tool you are using. There may be specific recommendations or best practices for managing log messages.
