• The SAP error message CNV20200015 indicates that during a data migration or conversion process, the system has detected that at least one table (in this case, the ONRAO table) contains identical data records. This situation can arise during data migration projects, especially when consolidating or transforming data from multiple sources.
  
  Cause:
  
  Duplicate Data: The most common cause of this error is the presence of duplicate records in the source data that are being migrated to the target system.
  Data Transformation Logic: If the data transformation logic is not correctly defined, it may lead to the generation of identical records.

  Solution:
  
  
  Identify Duplicates: 
  
  Analyze the source data to identify the duplicate records. You can use SQL queries or data profiling tools to find duplicates based on key fields.
