It's not possible to update existing line item Products via the Data Loader due to complications outlined in the article, Product mismatch in Quote's 'Quote Line Item' related list and Quote Line Item record.
As a workaround, it's possible to re-insert updated Quote Line Items as new records by exporting existing line items, updating the export file with the new Product's Price Book Entry Ids, inserting the new Quote Line Items associated to the new products, and then deleting the original Quote Line Items.
| Warning Always back up your data before performing any data operation. See Export Backup Data from Salesforce or Export Data for more details. It is recommended to run a test with a small subset of records to ensure the operation was successful through manually opening and verifying that the corresponding records are correct in Salesforce. |
1. Export existing Quote Line Item (QuoteLineItem) records using the Data Loader to Export Data.
Note: If Data Loader is not yet installed, please review Install Data Loader.
2. Rename the ID column in your export file to "OLD ID" and update the existing values in the PRICEBOOKENTRYID column with your desired new Product's corresponding PricebookEntryIds.
3. Once you have updated your existing Quote Line Item export file with your new Product's corresponding PricebookEntry Ids and saved it in Excel you're ready to re-insert the Quote Line Items with their updated products.
4. Now you'll need to delete the original Quote Line Items since you have now re-created them with your updated Products.
