• What is the cause and solution for SAP error message CNV_PE428 - Decimal place info already present for area &1 and target &2 ?

  The SAP error message CNV_PE428 indicates that there is an issue with the decimal place information for a specific area and target during a data conversion or migration process. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  The error message "Decimal place info already present for area &1 and target &2" suggests that the system has detected that decimal place information for the specified area (e.g., a specific field or data structure) and target (e.g., a target table or structure) is already defined or exists. This can happen due to:
  
  Duplicate Configuration: The decimal places for the specified area and target have been defined multiple times in the configuration.
  Incorrect Mapping: The mapping of fields during the data migration process may have been set up incorrectly, leading to conflicts in the definition of decimal places.
  Data Consistency Issues: There may be inconsistencies in the data being migrated, where the source data has different decimal place definitions than what is expected in the target.
  
  Solution:
  To resolve the CNV_PE428 error, you can take the following steps:
  
  
  Check Configuration: Review the configuration settings for the data migration process. Ensure that the decimal places for the specified area and target are defined only once and are consistent with the source data.
  
  
  Review Mapping: Go through the mapping of fields in the migration tool. Ensure that the fields are correctly mapped and that there are no conflicts in the definitions of decimal places.
  
  
  Data Validation: Validate the source data to ensure that it adheres to the expected formats and decimal place definitions. Correct any inconsistencies in the source data before attempting the migration again.
  
  
  Adjust Migration Settings: If necessary, adjust the migration settings to accommodate the existing decimal place information. This may involve modifying the target structure or the way data is being processed.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for any additional guidance or troubleshooting steps.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
