• What is the cause and solution for SAP error message CNV_20800225 - Only &1 messages being displayed.(Temporary duplicates check) ?

  The SAP error message CNV_20800225 indicates that there is a limitation in the number of messages being displayed due to a temporary duplicates check. This typically occurs during data migration or conversion processes, particularly when using SAP's tools for data transfer, such as the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error message is triggered when the system detects that there are too many messages (warnings, errors, or informational messages) generated during a data migration process. To prevent overwhelming the user with too many messages, the system limits the display to a certain number (in this case, only &1 messages are shown). This is a safeguard to ensure that users can focus on the most critical messages without being inundated by less important ones.
  Solution:
  
  
  Check Logs: Review the detailed logs of the migration process. Often, the logs will provide more information about the messages that are not displayed due to the limitation. You can access these logs through the transaction codes related to the migration tool you are using.
