• What is the cause and solution for SAP error message CNV_CMIS_A_20223 - Check content: Identical key with different values found in table. ?

  The SAP error message CNV_CMIS_A_20223 indicates that there is an issue with data consistency in a table during a data migration or conversion process. Specifically, it means that there are identical keys in the table that have different values associated with them. This can lead to ambiguity and inconsistency in the data, which is problematic for the integrity of the database.
  Cause:
  
  
  Duplicate Keys: The error typically arises when the same key (or primary key) is used for multiple records, but the values associated with those keys differ. This can happen due to:
  
  Data entry errors.
  Issues during data extraction from the source system.
  Inconsistent data formats or structures between the source and target systems.
  Merging of data from different sources without proper deduplication.
  
  
  
  Data Migration Issues: If you are migrating data from one system to another, the mapping or transformation rules may not have been correctly applied, leading to duplicate keys with different values.
  
  
  Solution:
  
  
  Identify Duplicate Keys: 
  
  Use SQL queries or data analysis tools to identify the records in the table that have the same key but different values. For example:
  SELECT key_column, COUNT(*)
  FROM your_table
  GROUP BY key_column
  HAVING COUNT(*) > 1;
  
  
  
  
  Analyze the Data: 
  
  Once you have identified the duplicates, analyze the records to understand why they differ. This may involve checking the source data or reviewing the data transformation logic.
  
  
  
  Resolve Conflicts: 
  
  Decide on a strategy to resolve the conflicts. This could involve:
  
  Merging the records into a single entry with a consistent value.
  Deleting duplicates if they are not needed.
  Updating the records to ensure that they are consistent.
  
  
  
  
  
  Data Cleansing: 
  
  Implement data cleansing processes to prevent similar issues in the future. This may include validation rules, deduplication processes, and better data governance practices.
  
  
  
  Re-run the Migration: 
  
  After resolving the duplicates, re-run the data migration or conversion process to ensure that the error does not occur again.
  
  
  
  Related Information:
