  Review Mapping Configuration: Check the mapping configuration in the migration tool. Ensure that all necessary mapping rules are defined and that they correctly correspond to the target system's data structure.
  Data Cleansing: Perform data cleansing on the source data to address any inconsistencies or errors. This may involve correcting data types, filling in missing values, or removing invalid entries.
  Check Document Types: Verify that all document types in the source system have corresponding types in the target system. If necessary, create new document types in the target system to accommodate the source data.
  Run Migration Simulation: Use the migration tool's simulation feature to identify potential issues before executing the actual migration. This can help pinpoint specific documents that are causing mapping failures.
  Consult Documentation: Refer to SAP's official documentation for the migration tool you are using. There may be specific guidelines or troubleshooting steps related to the CNV_20000246 error.
