• What is the cause and solution for SAP error message CNV_10100328 - Set value &1 exists more than once ?

  The SAP error message CNV_10100328 indicates that there is a duplicate entry for a value in a specific context, which is causing a conflict during a data migration or conversion 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 conversion programs.
  Cause:
  The error occurs when the system detects that a value (denoted as &1 in the error message) is present more than once in a dataset where unique values are expected. This could happen due to:
  
  Duplicate Records: The source data may contain duplicate entries for a key field that should be unique.
  Incorrect Mapping: The mapping of fields during the migration process may not be set up correctly, leading to multiple records being interpreted as the same.
  Data Quality Issues: Poor data quality in the source system can lead to duplicates that were not previously identified.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Review the dataset that is being migrated to identify where the duplicates are occurring. You can use SQL queries or data analysis tools to find duplicate entries based on the key field.
  
  
  
  Clean Up Data:
  
  Once duplicates are identified, you will need to decide how to handle them. Options include:
  
  Removing duplicates if they are not needed.
  Merging records if they contain complementary information.
  Adjusting the data to ensure that each entry is unique.
  
  
  
  
  
  Adjust Mapping:
  
  If the error is due to incorrect mapping, review the mapping configuration in the migration tool to ensure that fields are correctly aligned and that unique constraints are respected.
  
  
  
  Re-run Migration:
  
  After cleaning up the data and ensuring that there are no duplicates, re-run the migration process to see if the error persists.
