when updating a customer record through csv it keeps failing and error : this record exists

AI generated answer (using internal Slack threads):

When updating a customer record through CSV and you encounter the error "this record exists", it could be due to a few reasons: 1. Duplicated Keys: The error message suggests that there might be duplicate keys in your CSV file. Make sure that the internal IDs or any other unique identifiers used in your CSV file are unique and do not repeat. 2. Overwrite Sublist Option: If you are using the 'overwrite sublist' option, it will replace the entire sublist with the data from your CSV file. If there are duplicate line items in your CSV file, it could cause the import to fail. 3. Mapping of Fields: Ensure that the fields in your CSV file are correctly mapped to the fields in the NetSuite record. For example, if you are trying to update an address field, you might need to map the address ID since address is a separate record. If the ID for the address record is not mapped, then updates won't work. 4. Unsupported Records: Some records in NetSuite may not support CSV imports. If you are trying to update such a record, the import will fail. In such cases, you might need to use a script or a third-party tool like Celigo's integrator.io. Remember to always validate your CSV file before attempting the import to ensure that it is correctly formatted and does not contain any errors. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
