Does anyone know what permission I might be missing if I cannot see fields like

taxTotal

or

totalAfterTaxes

when retrieving SO's via the REST API? https://system.netsuite.com/help/helpcenter/en_US/APIs/REST_API_Browser/record/v1/2020.2/index.html#/definitions/salesOrder

Same problem here, this blog post here has some suggestions. https://timdietrich.me/blog/netsuite-suiteql-sales-tax/
