• What is the cause and solution for SAP error message CNV_10020105 - &1, source package &2: Required card. &3 is less than found card. &4 ?

  The SAP error message CNV_10020105 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates a mismatch in the expected number of records (or "cards") in a source package compared to what is actually found.
  Cause:
  The error message can be broken down as follows:
  
  Required card: This refers to the number of records that the system expects to find in the source data package.
  Found card: This indicates the actual number of records that were found in the source data package.
  The error occurs when the number of records found is less than the number of records required.
  
  This discrepancy can arise due to several reasons:
  
  Incomplete Data Extraction: The data extraction process may not have captured all the necessary records from the source system.
  Data Filtering: There may be filters applied that exclude certain records, leading to fewer records being available than expected.
  Configuration Issues: Incorrect configuration settings in the migration tool or process can lead to mismatches in expected versus actual records.
  Data Quality Issues: Missing or corrupted data in the source system can also lead to fewer records being available.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Verify Source Data: Check the source system to ensure that all required records are present. You may need to run queries or reports to confirm the completeness of the data.
  
  
  Review Migration Settings: Look into the configuration settings of the migration tool to ensure that they are set up correctly. Make sure that no unnecessary filters are applied that could exclude records.
  
  
  Data Extraction Process: If you are using a data extraction tool, ensure that the extraction process has completed successfully and that all records have been captured.
  
  
  Check for Data Quality Issues: Investigate any potential data quality issues in the source system that may be causing records to be missing. This may involve cleaning up the data or correcting any inconsistencies.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be additional troubleshooting steps or considerations specific to your scenario.
  
  
  Logs and Traces: Check the logs and traces generated during the migration process for any additional error messages or warnings that could provide more context about the issue.
