Failure to add serial number to a shipment allocation line

[junxie]

Hi!

We are trying to using the PUT to insert a serial number for a product in a shipment

Below is the relevant part of the result from the GET reponse

"shipmentDetailLines": [
    {
      "lineNumber": 1,
      "inventoryNumber": "IAC-RBAT-5KCINV-01",
      "freeItem": false,
      "warehouse": {
        "id": "108       ",
        "description": "Örebro"
      },
      "location": {
        "id": "1",
        "name": "Standard"
      },
      "uom": "STYCK",
      "shippedQty": 1,
      "orderedQty": 1,
      "openQty": 0,
      "lotSerialNbr": "",
      "description": "SolarEdge Cable set, Battery to Inverter",
      "allocations": [
        {
          "lineNbr": 2,
          "itemId": "IAC-RBAT-5KCINV-01",
          "location": {
            "id": "1",
            "name": "Standard"
          },
          "lotSerialNumber": "",
          "quantity": 1,
          "uom": "STYCK",
          "description": "SolarEdge Cable set, Battery to Inverter"
        }
      ],
      "orderLineNbr": 1,
      "alternateID": "IAC-RBAT-5KCINV-01"
    },
    {
      "lineNumber": 3,
      "inventoryNumber": "HVS",
      "freeItem": false,
      "warehouse": {
        "id": "108       ",
        "description": "Örebro"
      },
      "location": {
        "id": "1",
        "name": "Standard"
      },
      "uom": "STYCK",
      "shippedQty": 1,
      "orderedQty": 1,
      "openQty": 0,
      "description": "BYD HVS",
      "allocations": [
        {
          "lineNbr": 7,
          "itemId": "HVS",
          "location": {
            "id": "1",
            "name": "Standard"
          },
          "lotSerialNumber": "",
          "quantity": 1,
          "uom": "STYCK",
          "description": "BYD HVS"
        }
      ],
      "orderLineNbr": 2,
      "alternateID": "HVS"
    },
    {
      "lineNumber": 5,
      "inventoryNumber": "FRAKT",
      "freeItem": false,
      "warehouse": {
        "id": "108       ",
        "description": "Örebro"
      },
      "location": {
        "id": "1",
        "name": "Standard"
      },
      "uom": "STYCK",
      "shippedQty": 1,
      "orderedQty": 1,
      "openQty": 0,
      "lotSerialNbr": "",
      "description": "Frakt",
      "allocations": [
        {
          "lineNbr": 6,
          "itemId": "FRAKT",
          "location": {
            "id": "1",
            "name": "Standard"
          },
          "lotSerialNumber": "",
          "quantity": 1,
          "uom": "STYCK",
          "description": "Frakt"
        }
      ],
      "orderLineNbr": 3
    }
  ]

 It can be seen that the inside the shipment line 3, there is an allocation with lineNbr 7 which has an empty lotSerialNumber. All we want to do is to update the shipment so that a serial number is added. We tried many different approaches, but all failed:
1. Delete the existing empty allocation and insert a new one with a valid lotSerialNumber, see below payload for the PUT request.

Error: 'VismaId: eec30e73-81c6-438c-8dc6-588dafe9973f. Object reference not set to an instance of an object.' 

{
  "shipmentDetailLines": [
    {
      "lineNumber": {
        "value": 3
      },
      "operation": "Update",
      "allocations": [
        {
          "lineNbr": {
            "value": 7
          },
          "operation": "Delete",
        },
        {
          "lotSerialNumber": {
            "value": "P031T020W2407032144"
          },
          "operation": "Insert",
        },
      ]
    }
  ]
}

2. Update the exising empty allocation
Error: Shipment Allocation Line: '7' not found.

{
  "shipmentDetailLines": [
    {
      "lineNumber": {
        "value": 3
      },
      "operation": "Update",
      "allocations": [
        {
          "lineNbr": {
            "value": 7
          },
          "operation": "Update",
          "lotSerialNumber": {
            "value": "P031T020W2407032144"
          },
        }
      ]
    }
  ]
