This error indicates that there was a failure in importing the keys for a specific table, which can be due to various reasons.
  Causes:
  
  Data Integrity Issues: The data being imported may have integrity issues, such as duplicate keys or missing required fields.
  Incorrect Mapping: The mapping of fields between the source data and the target table may be incorrect, leading to failures in key imports.

  Review Configuration: Ensure that the DMC and the target system are correctly configured. Check for any settings that may affect the import process.
  Data Type Validation: Validate that the data types in the source data match the expected data types in the target table. Make necessary adjustments to the data format if needed.
