• What is the cause and solution for SAP error message CNV20551748 - Deletion criteria cannot be processed as &1 is present in No-Change table ?

  The SAP error message CNV20551748 indicates that there is an issue with the deletion criteria in a data migration or conversion process. Specifically, it suggests that the system is unable to process the deletion criteria because a certain entry (denoted as &1) is present in the No-Change table. This typically occurs during data migration scenarios, such as when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  
  No-Change Table: The No-Change table is used to track records that should not be altered during the migration process. If an entry is present in this table, it means that the system has determined that this record should remain unchanged, which conflicts with the deletion criteria you are trying to apply.
  Data Integrity: The presence of the entry in the No-Change table may indicate that the data is critical or that it has dependencies that prevent it from being deleted.
  
  Solution:
  
  Review the No-Change Table: Check the No-Change table to understand why the specific entry is marked as no-change. You can do this by accessing the relevant migration or conversion logs.
  Adjust Deletion Criteria: If the entry is indeed necessary and should not be deleted, you may need to adjust your deletion criteria to exclude this entry.
  Modify Migration Settings: If you believe that the entry should be eligible for deletion, you may need to modify the migration settings or the logic that populates the No-Change table.
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for more detailed guidance on handling No-Change entries.
  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 insights based on your specific scenario.
