How to fix this error?

Check your mapping table for correctness.
If the mapping is correct, be aware that the conversion runtime might be

CNV_40300017 - Details

• The SAP error message CNV_40300017 indicates that during a data migration or conversion process, the mapping of values has resulted in temporary duplicates. This typically occurs in scenarios where data is being transformed or migrated from one system to another, and the mapping logic does not ensure uniqueness for certain fields.
  
  Cause:
  
  Duplicate Values in Source Data: The source data may contain duplicate entries that are not being handled correctly during the mapping process.
  Mapping Logic Issues: The mapping rules defined in the conversion process may not account for uniqueness, leading to the creation of duplicate records in the target system.
  Configuration Errors: Incorrect configuration settings in the migration tool or process can lead to unintended duplicates.
  Data Transformation Errors: Errors in the transformation logic that do not properly differentiate between records can also lead to duplicates.
  
  
  Solution:
  
  Review Source Data: Check the source data for duplicates. If duplicates exist, you may need to clean the data
