CNV808 - Details

• The SAP error message CNV808 "Table &1 already exists" typically occurs during data migration or conversion processes, particularly when using SAP's Data Migration tools or during the execution of a conversion program. This error indicates that the system is attempting to create a database table that already exists in the database.
  
  Cause:
  
  Table Already Exists: The most straightforward cause is that the table you are trying to create already exists in the database. This can happen if the migration process was partially completed or if the table was created in a previous run.
  Incorrect Migration Setup: The migration setup might not be correctly configured, leading to attempts to create tables that should not be created again.
  Multiple Runs: If the migration process is run multiple times without proper cleanup, it can lead to this error.
  
  
  Solution:
  
  Check for Existing Tables: Before running the migration or conversion program, check if the table already exists in the database.
