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.
Cause: 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.
Configuration Issues: There may be configuration settings in the target SAP system that enforce unique constraints on account assignments, leading to this error when duplicates are detected.
Solution: Data Cleansing: Review the source
