  The SAP error message CNV_20310_CHECK034: No mapping provided typically occurs during data migration or conversion processes, particularly when using SAP's Conversion Tools or the SAP S/4HANA Migration Cockpit. This error indicates that there is a missing mapping for a specific field or data element that is required for the conversion process.
  Cause:
  
  
  Missing Mapping Configuration: The most common cause of this error is that the mapping for a specific field has not been defined in the migration or conversion settings. This can happen if the source and target systems have different structures or if the mapping was not set up correctly.

  Solution:
  
  
  Check Mapping Configuration: Review the mapping configuration in the migration tool. Ensure that all required fields have been mapped correctly from the source to the target. You may need to manually define mappings for any fields that are missing.
  
  
  Update Data Source: Ensure that the data source you are using for the migration contains all the necessary fields and that they are correctly populated. If necessary, update the data source to include the required fields.
  
  
  Data Type Compatibility: Verify that the data types of the source and target fields are compatible. If there are discrepancies, you may need to adjust the data types in the source or target system.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or requirements for mapping that you need to follow.
  
  
  Testing: After making changes, run a test migration to ensure that the error has been resolved and that the data is being mapped correctly.
