• What is the cause and solution for SAP error message ADW128 - Data records could not be deserialized ?

  The SAP error message ADW128, which states "Data records could not be deserialized," typically occurs in the context of data processing, particularly when dealing with data transfer or integration scenarios in SAP systems. This error indicates that the system encountered an issue while trying to convert serialized data back into its original format (deserialization).
  Causes:
  
  Data Format Issues: The serialized data may not match the expected format or structure. This can happen if there are changes in the data structure or if the data was corrupted during transmission.
  Version Mismatch: If the data was serialized using a different version of the application or data model, the deserialization process may fail due to incompatibility.
  Missing Fields: Required fields in the serialized data may be missing or null, leading to deserialization errors.
  Data Type Mismatches: If the data types in the serialized data do not match the expected data types in the target structure, deserialization will fail.
  Configuration Issues: Incorrect configuration settings in the SAP system or middleware can lead to deserialization problems.
  
  Solutions:
  
  Check Data Format: Ensure that the serialized data is in the correct format and adheres to the expected structure. Validate the data before attempting to deserialize it.
  Version Compatibility: Verify that the version of the application or data model used for serialization matches the version used for deserialization. If there are discrepancies, consider updating the application or data model.
  Review Required Fields: Check the serialized data for any missing required fields. Ensure that all necessary data is present and correctly formatted.
  Data Type Validation: Confirm that the data types in the serialized data match the expected data types in the target structure. If there are mismatches, correct the data accordingly.
  Configuration Review: Review the configuration settings in the SAP system and any middleware involved in the data transfer process. Ensure that all settings are correctly configured for serialization and deserialization.
  Error Logs: Check the SAP application logs (transaction SLG1) for more detailed error messages that can provide additional context about the deserialization failure.
