How to Check Sales Order Line Item History in NetSuite Integration Without System Notes Access

Hi @here, any NetSuite integration users here? I created a Sales Order with 2 line items through our integration, but it now shows only 1. I'd like to find out when and how the second line was removed. I don't have permission to view the history (Show Activity / System Notes) in the UI, and the integration role can't access System Notes through the API (SuiteQL on systemnote fails). Is there any other way to check the record's history before I reach out to the customer?
