• What is the cause and solution for SAP error message CNV_DMC_SIN451 - Only one characteristic format is supported for each record ?

  The SAP error message CNV_DMC_SIN451 indicates that there is an issue with the data format being used in a data migration or conversion process, specifically related to the handling of characteristics in the data records. This error typically arises when the system encounters multiple characteristic formats within a single record, which is not supported.
  Cause:
  The primary cause of this error is that the data being processed contains more than one characteristic format in a single record. In SAP data migration scenarios, especially when using tools like the Data Migration Cockpit (DMC) or other conversion tools, each record is expected to conform to a specific format that includes only one characteristic type. If the record includes multiple formats or types of characteristics, the system cannot process it correctly, leading to this error.
  Solution:
  To resolve the CNV_DMC_SIN451 error, you can take the following steps:
  
  
  Review the Data Source: Check the source data that you are trying to migrate. Ensure that each record adheres to the expected format and contains only one characteristic format.
  
  
  Data Cleansing: If you find records with multiple characteristic formats, you will need to clean the data. This may involve:
  
  Splitting records that contain multiple formats into separate records.
  Ensuring that each record only contains one characteristic format.
  
  
  
  Mapping Configuration: Review the mapping configuration in your migration tool. Ensure that the mapping is set up correctly to handle the characteristics as intended.
  
  
  Testing: After making the necessary adjustments to the data, perform a test migration with a small subset of the data to ensure that the error does not occur again.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for any additional guidelines or requirements regarding characteristic formats.
  
  
  Seek Support: If the issue persists after following the above steps, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
