• What is the cause and solution for SAP error message CNV20551425 - Deletion criteria cannot be processed due to entry in 'no-change' table ?

  The SAP error message CNV20551425 indicates that there is an issue with the deletion criteria in a data migration or conversion process, specifically related to entries in a 'no-change' table. This typically occurs during data migration activities, such as using the SAP S/4HANA Migration Cockpit or other data transfer tools.
  Cause:
  The error arises when the system detects that there are entries in a 'no-change' table that prevent the deletion of certain records. 'No-change' tables are those that are protected from changes during the migration process to ensure data integrity. This means that certain records cannot be deleted or modified if they are referenced in these tables.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the No-Change Table: Determine which 'no-change' table is causing the issue. This information may be available in the error message details or logs.
  
  
  Check Data Dependencies: Review the data in the identified 'no-change' table to understand why the entries are preventing the deletion. Look for any foreign key relationships or dependencies that might be causing the issue.
  
  
  Adjust Deletion Criteria: If possible, modify the deletion criteria to exclude the records that are causing the conflict. This may involve changing the selection criteria in your migration or conversion process.
  
  
  Data Cleanup: If the entries in the 'no-change' table are no longer needed, consider cleaning up the data. However, be cautious with this approach, as it may affect data integrity.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific guidelines or best practices for handling 'no-change' tables.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who can provide guidance based on your specific scenario.
