  The SAP error message CNV20201200 typically relates to data conversion issues during a migration or data transfer process. This specific error indicates that there are alphanumeric limits being exceeded for a particular object and sub-object in the context of a data migration scenario.
  Cause:
  
  Data Length Exceeded: The error suggests that the data being processed exceeds the defined alphanumeric limits for the specified object (&1) and sub-object (&2). This could happen if the source data contains longer strings than what the target system can accommodate.
  Incorrect Mapping: There may be an issue with how the data is mapped from the source to the target system, leading to data that does not conform to the expected formats or lengths.
  Configuration Issues: The configuration settings for the data migration might not be aligned with the actual data being processed.
  
  Solution:
  
  Check Data Lengths: Review the data being migrated to ensure that it adheres to the length restrictions defined in the target system. You may need to truncate or modify the data to fit within the limits.
  Adjust Mapping: If the mapping of fields between the source and target systems is incorrect, adjust it to ensure that the data fits the expected formats and lengths.
  Review Configuration: Check the configuration settings for the migration process to ensure they are set up correctly. This may involve reviewing the migration tool settings or the specific parameters used in the migration.
  Consult Long Text: The error message suggests checking the "long text" for more detailed information. This can provide additional context or specific instructions related to the error.
  Data Cleansing: If the data contains invalid characters or formats, consider performing data cleansing before the migration process.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on data migration best practices.
  Migration Tools: If you are using a specific SAP migration tool (like SAP S/4HANA Migration Cockpit), refer to the documentation for that tool for additional troubleshooting steps.
  Testing: Conduct thorough testing with a subset of data to identify potential issues before performing a full migration.
  
  If the problem persists after trying the above solutions, it may be beneficial to engage with SAP support or consult with a technical expert familiar with the specific migration scenario you are dealing with.
