  The SAP error message CNV20200146 indicates that a conversion routine is not defined for a specific table during a data migration or conversion process. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.

  Check Migration Settings:
  
  Review the migration settings and mappings to ensure that all necessary conversion routines are correctly assigned to the relevant tables.
