Another Item Receipt question: I’m attempting to replace all of the lines on an IR with the following REST command: Calling NetSuite API: PATCH URL Uri: record/v1/itemreceipt/1361309) [dd.service=rails dd.trace_id=3537402724481768748 dd.span_id=0] Headers: {“Authorization”=>“REDACTED”, “Content-Type”=>“application/json”, “Accept”=>“application/json”} Request Body: {“item”{“items”[{“item”{“id”“642”},“quantity”3.0},{“item”{“id”“645”},“quantity”10.0}]}} Params: {:replaceSelectedFields=>true, :replace=>“item”} [dd.service=rails dd.trace_id=3537402724481768748 dd.span_id=0] Error while accessing a resource. You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist. Error code: USER_ERROR Path: item Is the “item” sublist on an Item Receipt considered static? I can update the quantity on an existing line just fine. 1. But can I not replace the entire “item” sublist? 2. Will I be able to add a line with a new item if I need to?

Items on Receipts are tied directly to the lines on the Purchase Orders, this is a hard restriction (and appropriately so) of NetSuite. You cannot add, edit, or remove the items themselves.

The general rule of thumb is of you can't do it in the UI you can't do it via API

You can edit them, but you can’t replace them wholesale.
