The SAP error message CNV_PE470 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 are worklist items that are grouped together but have different values for a specific field (denoted by &3 in the error message). This can lead to inconsistencies in the data being processed.
Cause: The error is usually caused by: Inconsistent Data: The worklist items being processed have different values for a field that is expected to be uniform across the group. For example, if you are migrating customer data, and the worklist contains customers from different regions or with different account types, this inconsistency can trigger the error. Incorrect Grouping Logic: The logic used to group the worklist items may not be appropriate for the data being processed, leading to items that should not be grouped together being treated as a single unit.
