• What is the cause and solution for SAP error message CNV20410048 - Source table &1 is missing in CNVTABLES ?

  The SAP error message CNV20410048 indicates that a source table specified in a conversion process is missing from the CNVTABLES table. This error typically occurs during data migration or conversion activities, particularly when using SAP's data migration tools.
  Cause:
  
  
  Missing Table Entry: The source table that is referenced in the conversion process does not have a corresponding entry in the CNVTABLES table. This could be due to:
  
  The table not being included in the migration project.
  The table being incorrectly defined or not defined at all in the conversion settings.
  A misconfiguration in the migration project.
  
  
  
  Incorrect Configuration: The configuration for the data migration might not have been set up correctly, leading to the system not recognizing the source table.
  
  
  Transport Issues: If the migration project was transported from one system to another, there might have been issues during the transport that caused the table definitions to be lost.
  
  
  Solution:
  
  
  Check CNVTABLES: Verify that the source table is indeed missing from the CNVTABLES table. You can do this by executing a query on the CNVTABLES table in the SAP system.
  
  
  Add Missing Entry: If the table is missing, you may need to add the appropriate entry for the source table in the CNVTABLES table. This typically involves:
  
  Identifying the correct structure and attributes for the source table.
  Using the appropriate transaction (like SE11 or SE16) to add the entry.
  
  
  
  Review Migration Project Configuration: Ensure that the migration project is correctly configured to include the source table. Check the settings and mappings to ensure that all necessary tables are included.
  
  
  Consult Documentation: Refer to the SAP documentation or guides related to the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for detailed instructions on how to configure source tables.
  
  
  Check for Transport Issues: If the migration project was transported, check the transport logs for any errors or warnings that might indicate why the source table is missing.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a critical migration process.
