• What is the cause and solution for SAP error message CNV_20900221 - Only &2 messages being displayed in log. ?

  The SAP error message CNV_20900221 indicates that there are too many messages being logged during a conversion process, and as a result, only a limited number of messages (in this case, &2) are being displayed in the log. This is typically encountered during data migration or conversion activities, especially when using SAP's data migration tools.
  Cause:
  
  Excessive Log Messages: The conversion process is generating a large number of log messages, exceeding the display limit set in the system.
  Configuration Settings: The logging settings in the SAP system may be configured to limit the number of messages displayed or stored.
  Performance Optimization: To optimize performance, the system may restrict the number of messages shown to avoid overwhelming the user with information.
  
  Solution:
  
  
  Increase Log Display Limit: 
  
  You can adjust the settings in the SAP system to increase the number of messages that can be displayed in the log. This can typically be done in the configuration settings of the data migration tool you are using.
  Check the relevant parameters in transaction RZ10 or RZ11 to see if there are any settings related to log message limits.
  
  
  
  Review Log Files: 
  
  Instead of relying solely on the displayed messages, check the log files directly. These logs may contain all messages generated during the conversion process, even those not displayed in the user interface.
  You can access detailed logs through transaction codes like SLG1 (Application Log) or by navigating to the specific log files in the file system.
  
  
  
  Filter Messages: 
  
  If the log is too verbose, consider filtering the messages to focus on warnings or errors that are more critical to your conversion process.
  
  
  
  Consult Documentation: 
  
  Review the documentation for the specific data migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for any specific recommendations regarding logging and message display.
  
  
  
  Contact SAP Support: 
  
  If the issue persists or if you need further assistance, consider reaching out to SAP Support for guidance tailored to your specific situation.

  Best Practices: Follow best practices for data migration, including proper planning, testing, and monitoring of the migration process to minimize issues.
