The SAP error message CNV_DMC_SIN243: Wrong Class Type &1. Only supports batch and material typically occurs during data migration or conversion processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the system encountered a class type that is not supported for the operation being performed.
Cause: Unsupported Class Type: The error suggests that the class type being processed is neither a batch class nor a material class. The DMC is designed to handle specific class types, and if the data being migrated includes a different class type, this error will be triggered. Data Mapping Issues: There may be a mismatch in the data mapping configuration, where the source data does not align with the expected class types in the target system. Configuration Errors: Incorrect configuration settings in the migration project could lead to the system expecting a different class type than what is being provided.
Solution: Check Class
