• What is the cause and solution for SAP error message CNV_20110008 - Accounts are unique ?

  The SAP error message CNV_20110008: Accounts are unique typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is an issue with the uniqueness of account assignments in the data being processed.

  Duplicate Account Entries: The error usually arises when there are duplicate entries for accounts in the source data that are being migrated. This can happen if the same account is assigned to multiple records or if there are inconsistencies in the data.
  Data Mapping Issues: If the mapping of accounts from the legacy system to the target system is not correctly defined, it can lead to conflicts where the same account is being referenced multiple times.

  Data Cleansing: Review the source data for duplicates. Ensure that each account is unique and that there are no multiple entries for the same account. You may need to consolidate or remove duplicate records.
  Check Mapping: Verify the mapping of accounts from the legacy system to the target system. Ensure that each account is correctly mapped and that there are no overlaps or conflicts.
  Adjust Configuration: If necessary, review the configuration settings in the target SAP system to understand the uniqueness constraints. Adjust these settings if appropriate, but be cautious as this may have broader implications.
  Use Migration Tools: Utilize SAP's migration tools effectively. They often have built-in checks and validations that can help identify issues before the actual migration takes place.
  Testing: Conduct thorough testing in a development or sandbox environment before performing the migration in the production environment. This can help identify and resolve issues without impacting live data.
