The SAP error message CNV_PE_CHECK030 typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is a worklist item that has a status but does not have a corresponding status in the worklist itself.

Cause: Data Inconsistency: The worklist item may have been created or modified in a way that does not align with the expected statuses in the worklist. Incomplete Migration: If the migration process was interrupted or not completed successfully, it could lead to orphaned worklist items.
Configuration Issues: There may be configuration issues in the migration cockpit or the related tools that lead to mismatched statuses. Custom Development: If there are custom developments or enhancements in the migration process, they might not be properly aligned with standard processes.
