Last ditch effort here When attempting to update an itemreceipt via REST i keep getting the following response:

{
  "type": "<https://www.rfc-editor.org/rfc/rfc9110.html#section-15.5.1>",
  "title": "Bad Request",
  "status": 400,
  "o:errorDetails": [
    {
      "detail": "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.",
      "o:errorPath": "item",
      "o:errorCode": "USER_ERROR"
    }
  ]
}

My Payload is:

{
  "item": {
    "items": [
      {
        "orderLine": 1,
        "location": 3
      },
      {
        "orderLine": 2,
        "location": 3
      }
    ]
  }
}

doing PATCH /itemReceipt/{receiptID}

not an expert in this area but I'm pretty sure NS doesn't support PATCH

Have been using it in other places fine, i've since spotted the issue is actually with line id generation, line 1 works fine, the 2nd line is called Line 4 for reasons totally unknown 🤷

are you doing a get before to know what line to update?

the line field refers to the line id

Yeah I guess the question is what is the originating transaction if the item receipt. PO and TO behave differently

I've been trying to work out what determines the sequence. Turns out there is just no rhyme or reason, or at least nothing that can be guessed.
