• What is the cause and solution for SAP error message /SMB/CM_CONVERSION002 - Import table contains records already existing in database ?

  The SAP error message /SMB/CM_CONVERSION002 indicates that during an import operation, the system has detected that the import table contains records that already exist in the database. This typically occurs when you are trying to import data into a table that has unique constraints or primary keys, and the records being imported conflict with existing records.
  Cause:
  
  Duplicate Records: The import data contains records with primary key values that already exist in the target database table.
  Data Integrity Constraints: The target table has constraints (like unique keys) that prevent the insertion of duplicate records.
  Incorrect Data Preparation: The data being imported may not have been properly filtered or deduplicated before the import process.
  
  Solution:
  
  Identify Duplicates: Before importing, check the data you are trying to import for duplicates. You can do this by querying the target table to see which records already exist.
  Modify Import Data: Remove or modify the duplicate records in the import data. Ensure that the records you are trying to import have unique keys that do not conflict with existing records.
  Use Update Instead of Insert: If the intention is to update existing records rather than insert new ones, consider using an update operation instead of an insert.
  Error Handling: Implement error handling in your import process to manage duplicates gracefully, such as logging the duplicates and skipping them during the import.
  Check Import Logic: Review the logic of your import program or process to ensure it is designed to handle existing records appropriately.
  
  Related Information:
  
  Transaction Codes: Depending on the context, you might be using transaction codes like SE38 (ABAP Editor) or SE11 (Data Dictionary) to manage your import programs or data structures.
  Data Migration Tools: If you are using data migration tools (like LSMW, BAPIs, or BDC), ensure that the settings are configured to handle existing records correctly.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to your version of SAP or the import process you are using.
  Documentation: Review the documentation for the specific import method you are using to understand how it handles existing records.
  
  By following these steps, you should be able to resolve the error and successfully complete your import operation.
