• What is the cause and solution for SAP error message FINS_FI_MIG357 - Already existing record to be inserted for table &1 and key &2: &3 ?

  The SAP error message FINS_FI_MIG357 indicates that there is an attempt to insert a record into a database table that already contains a record with the same key. This typically occurs during data migration or data upload processes, where the system is trying to insert a new entry that conflicts with an existing one.
  Cause:
  
  Duplicate Key: The primary cause of this error is that the key (or combination of fields that make up the key) for the record you are trying to insert already exists in the target table.
  Data Migration Issues: This can happen during data migration processes where the source data may have duplicates or the target system already has records that were not accounted for.
  Incorrect Data Preparation: If the data being uploaded was not properly cleaned or validated before the upload, it may contain duplicates.
  
  Solution:
  
  
  Check Existing Records: Before attempting to insert the new record, check the target table to see if a record with the same key already exists. You can do this by querying the table using the key values.
  SELECT * FROM <table_name> WHERE <key_field> = '<key_value>';
  
  
  Data Cleansing: If duplicates are found in the source data, you will need to clean the data to ensure that only unique records are being inserted. This may involve removing duplicates or merging records as necessary.
  
  
  Update Instead of Insert: If the intention is to update an existing record rather than insert a new one, modify your process to perform an update operation instead of an insert.
  
  
  Error Handling in Migration: If you are using a migration tool or program, implement error handling to skip records that cause this error or log them for further investigation.
  
  
  Consult Documentation: Review the relevant SAP documentation or migration guides for specific instructions related to the data you are working with.
  
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may want to use transaction codes like SE11 (Data Dictionary) to check the structure of the table or SE16 (Data Browser) to view existing records.
  Migration Tools: If you are using SAP tools like LSMW (Legacy System Migration Workbench) or SAP Data Services, ensure that you are following best practices for data migration.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling data migration issues.
  
  By following these steps, you should be able to resolve the error and successfully manage your data migration or upload process.
