  The SAP error message CNV_20900083 indicates that during a data conversion process, the system has encountered an issue related to temporary duplicates in a specific table. This message is part of the SAP Conversion Tools, which are often used during system migrations or upgrades, particularly in the context of SAP S/4HANA migrations.
  Cause:
  The error message suggests that the conversion process expected to find a flag indicating that there were no temporary duplicates for the specified table (denoted as &1 in the message). The absence of this flag can occur due to several reasons:
  
  Data Integrity Issues: There may be actual duplicate entries in the source data that need to be resolved before the conversion can proceed.
  Configuration Issues: The conversion settings or parameters may not be correctly configured, leading to the system not recognizing the absence of duplicates.
  Process Interruption: If the conversion process was interrupted or not completed successfully in a previous run, it might leave the system in an inconsistent state.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Review the data in the specified table to identify any actual duplicate entries. You can use SQL queries or SAP transaction codes (like SE16 or SE11) to analyze the data.
  If duplicates are found, you will need to clean up the data by either deleting or merging the duplicate records.
  
  
  
  Review Conversion Logs:
  
  Check the logs generated during the conversion process for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Reconfigure Conversion Settings:
  
  Ensure that the conversion settings are correctly configured. This may involve reviewing the parameters set for the conversion process and making adjustments as necessary.
  
  
  
  Rerun the Conversion:
  
  After addressing any data integrity issues and ensuring the configuration is correct, rerun the conversion process to see if the error persists.
