Updating PurchaseDownPayments with a service layer error: "Unallowed item cost [DPO1.INMPrice]

[shine_chen]

hello：

I encountered an error while updating my PurchaseDownPayments using the service layer, prompting "Unallowed item cost [DPO1. INMPrice][line: 1]"

My steps are as follows:

1. A PurchaseDownPayments was added, POST :https://IP:50000/b1s/v1/PurchaseDownPayments,code:

{
   "DocDate":"2024-12-24",
    "U_HBYID":"YFK2412240004",
    "DocumentLines":[
        {
            "InventoryQuantity":20,
            "TaxTotal":28.99,
            "ItemCode":"111020031",
            "VatGroup":"J2",
            "LineNum":1,
            "BaseType":-1,
            "Price":11.150442,
            "PriceAfterVAT":12.6,
            "LineTotal":223.01,
            "GrossTotal":252,
            "LastBuyInmPrice": 0.0,
            "StockInmPrice": 0.0,
            "UnitsOfMeasurment":1
        },
        {
            "InventoryQuantity":30,
            "TaxTotal":34.51,
            "ItemCode":"111020031",
            "VatGroup":"J2",
            "LineNum":2,
            "BaseType":-1,
            "Price":8.849558,
            "PriceAfterVAT":10,
            "LineTotal":265.49,
            "GrossTotal":300,
            "LastBuyInmPrice": 0.0,
            "StockInmPrice": 0.0,
            "UnitsOfMeasurment":1
        }
    ],
    "TaxDate":"2024-12-24",
    "Comments":"",
    "BPL_IDAssignedToInvoice":1,
    "DownPaymentType":"dptRequest",
    "CardCode":"S0000006",
    "DocDueDate":"2024-12-24",
    "DocTotal":552
}

 2. I changed the ratio to 80% in the client

3. I used the service layer for patch update, PATCH :https://IP:50000/b1s/v1/PurchaseDownPayments,code:

{
   "DocDate":"2024-12-24",
    "U_HBYID":"YFK2412240004",

            "InventoryQuantity":20,
            "TaxTotal":28.99,
            "ItemCode":"111020031",
            "VatGroup":"J2",
            "LineNum":1,
            "BaseType":-1,
            "Price":11.150442,
            "PriceAfterVAT":12.6,
            "LineTotal":223.01,
            "GrossTotal":252,
            "LastBuyInmPrice": 0.0,
            "StockInmPrice": 0.0,
            "UnitsOfMeasurment":1
        },
        {
            "InventoryQuantity":30,
            "TaxTotal":34.51,
            "ItemCode":"111020031",
            "VatGroup":"J2",
            "LineNum":2,
            "BaseType":-1,
            "Price":8.849558,
            "PriceAfterVAT":10,
            "LineTotal":265.49,
            "GrossTotal":300,
            "LastBuyInmPrice": 0.0,
            "StockInmPrice": 0.0,
            "UnitsOfMeasurment":1
        }
    ],
    "TaxDate":"2024-12-24",
    "Comments":"",
    "BPL_IDAssignedToInvoice":1,
    "DownPaymentType":"dptRequest",
    "CardCode":"S0000006",
    "DocDueDate":"2024-12-24",
    "DocTotal":552
}

Then I got an error and the version I was using was 2411.

The above operations I can directly operate in the client successfully.

Same operation I can update on the client side.

Hi shine_chen,

Can you check the LineTotal value in the JSON request?

It can be caused by the incorrect LineTotal value which you are trying to set.

Kind regards,

Hi ANKIT_CHAUHAN

You mean I shouldn't pass this value?
