• What is the cause and solution for SAP error message CNV_10020561 - &1 (new) data was imported; file contained &2 rows ?

  The SAP error message CNV_10020561 typically relates to data import issues during a data migration or conversion process, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit. The message indicates that new data was imported, but there was a discrepancy in the number of rows expected versus the number of rows actually processed.
  Cause:
  
  Data Format Issues: The file being imported may not be in the expected format, leading to issues in reading the data correctly.
  Data Validation Errors: Some rows in the file may not meet the validation criteria set in the target system, causing them to be ignored or rejected.
  Duplicate Entries: If the system detects that the data being imported contains duplicates that violate unique constraints, it may skip those entries.
  Configuration Issues: There may be configuration settings in the migration tool that are not aligned with the data being imported.
  File Size Limitations: The file may exceed size limitations, causing only a portion of the data to be processed.
  
  Solution:
  
  Check the Data File: Review the data file for formatting issues, such as incorrect delimiters, missing headers, or invalid data types.
  Validate Data: Ensure that all data entries meet the validation rules of the target system. This may involve checking for required fields, data types, and unique constraints.
  Review Logs: Check the migration logs for detailed error messages that can provide insights into which rows were not processed and why.
  Adjust Configuration: If necessary, adjust the configuration settings in the migration tool to better align with the data being imported.
  Test with Smaller Files: If the file is large, try importing a smaller subset of the data to isolate the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any known issues or additional troubleshooting steps.
