  The SAP error message CNV_10100228 indicates that there is a problem with duplicate records in the context of set class assignments during a data migration or conversion process. This error typically arises when the system detects that new set names assigned to a particular set class are duplicating existing records, which can lead to inconsistencies in the data.
  Cause:
  
  Duplicate Set Names: The error is triggered when the new set names being assigned to a set class already exist in the system. This can happen if the same set name is being used for different records or if there are multiple entries with the same name in the migration data.
  Data Migration Issues: During data migration, if the source data contains duplicates or if the mapping of new set names is not correctly defined, it can lead to this error.
  Configuration Errors: Incorrect configuration of the set classes or the way they are defined in the system can also lead to this issue.
  
  Solution:
  
  Identify Duplicates: Review the set names being assigned to the set class. Check for any duplicates in the source data or in the target system. You can use transaction codes like SE16 or SE11 to query the relevant tables.
  Modify Set Names: If duplicates are found, modify the new set names to ensure they are unique. This may involve renaming some of the set names in your migration data.
  Adjust Mapping: If you are using a mapping file or tool for the migration, ensure that the mapping is correctly defined and does not lead to duplicate assignments.
  Data Cleansing: Before migration, perform data cleansing to remove or consolidate duplicate records in the source data.
  Testing: After making the necessary adjustments, re-run the migration process in a test environment to ensure that the error does not occur again.
