  The SAP error message CNV_20800085 indicates that during a data conversion process, the system has detected that the "No temporary duplicates during conversion" flag for a specific table (denoted as &1) has been set. This typically occurs in the context of data migration or conversion projects, especially when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error is caused by the following reasons:

  Consult Documentation: Refer to the SAP documentation related to the specific migration or conversion tool you are using. There may be specific guidelines or best practices for handling duplicates.
  
  
  Testing: After making the necessary changes, perform a test run of the conversion process to ensure that the error does not occur again.
