• What is the cause and solution for SAP error message CNV_CMIS_M009 - An entry with these key values already exists ?

  The SAP error message CNV_CMIS_M009 typically indicates that there is an attempt to create or insert a record in the database that already exists, based on the key values being used. This error is often encountered during data migration or conversion processes, particularly when using SAP's Conversion Tools or during the execution of specific programs that handle data entries.
  Cause:
  
  Duplicate Entries: The most common cause is that the data being processed contains duplicate entries for the key fields that are supposed to be unique.
  Data Migration Issues: If you are migrating data from another system, it is possible that the source data has duplicates that were not identified before the migration.
  Incorrect Mapping: There may be an issue with how the data is mapped from the source to the target system, leading to attempts to insert existing records.
  Concurrency Issues: If multiple processes are trying to insert the same record simultaneously, this can lead to conflicts.
  
  Solution:
  
  Identify Duplicates: Check the source data for duplicates. You can use SQL queries or data analysis tools to identify records that have the same key values.
  Data Cleansing: Clean the data before migration. Remove or consolidate duplicate records as necessary.
  Adjust Mapping: Review the mapping of fields between the source and target systems to ensure that the correct unique keys are being used.
  Error Handling: Implement error handling in your data migration process to catch and log these errors, allowing you to address them without stopping the entire process.
  Use of Update Instead of Insert: If the intention is to update existing records rather than insert new ones, ensure that the process is set to perform updates where applicable.
  Check for Existing Records: Before attempting to insert a new record, check if a record with the same key already exists in the target system.
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may want to look into transaction codes like SE11 (Data Dictionary), SE16 (Data Browser), or SE80 (Object Navigator) to analyze the database tables involved.
