The SAP error message
/IPRO/DBMC321 Cannot add duplicates
typically occurs in the context of the SAP Data Management Console (DMC) or when working with database management tasks in SAP. This error indicates that there is an attempt to add a duplicate entry to a database table or a data structure that does not allow duplicates.Cause:
- Duplicate Entries: The most common cause is that the data being inserted or updated already exists in the database, violating a unique constraint.
- Data Integrity Issues: There may be issues with the data integrity, where the same record is being processed multiple times.
- Configuration Errors: Incorrect configuration settings in the DMC or related tools may lead to attempts to add duplicate entries.
- Batch Processing: If you are processing data in batches, it is possible that the same record is included in multiple batches.
Solution:
- Check for Duplicates: Before attempting to add new entries, check the database for existing records that may cause duplicates. You can run a query to identify existing records.
- Modify Data: If duplicates are found, modify the data to ensure that it is unique before attempting to add it again.
- Adjust Configuration: Review the configuration settings in the DMC or related tools to ensure that they are set up correctly to prevent duplicate entries.
- Error Handling: Implement error handling in your data processing logic to catch and manage duplicate entries gracefully.
- Data Cleansing: If you are importing data, consider performing data cleansing to remove duplicates before the import process.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
