Hello #C298P0BCK, Does anybody know what is the field ID to set the item location for a line item into a sales order in Netsuite using SuiteScript 2.1? I'm using the code below -with the field 'inventorylocation'- to add an item to a sales order but it doesn't take the ID I'm passing through the parameters. The salesOrderObj is NOT charged dynamically. Everything is working except setting the location.

/**
 * Adds an item to the sales order record being created.
 * @param salesOrderObj Object referring the sales order record the item belongs to.
 * @param itemId The ID of the item to be added.
 * @param line The position of the item within the sales order items sublist.
 * @param expectedShipDate The shipping date of the order the item belongs to.
 */
public addItem(salesOrderObj, itemId, line, ItemInfo, expectedShipDate: Date, subsidiary, locationId) {
    try {
        let countryCode = this.nsHelper.searchCountry(this.customer.customerInfo.Address.Country);

        // Inserting a new item (line) to the items sublist of the order
        salesOrderObj.insertLine({
            sublistId: 'item',
            line: line
        });

        // Setting the item through its internal ID.
        salesOrderObj.setSublistValue({
            sublistId: 'item',
            fieldId: 'item',
            value: itemId,
            line: line
        });

        // Defining the quantity of items the customer bought.
        salesOrderObj.setSublistValue({
            sublistId: 'item',
            fieldId: 'quantity',
            value: ItemInfo.Quantity,
            line: line
        });

        // Defining the expected ship date of the item the customer bought.
        salesOrderObj.setSublistValue({
            sublistId: 'item',
            fieldId: 'expectedshipdate',
            value: expectedShipDate,
            line: line
        });

        // Defining the location of the item the customer bought.
        salesOrderObj.setSublistValue({
            sublistId: 'item',
            fieldId: 'inventorylocation',
            value: locationId,
            line: line
        });

        // Defining the total amount to be paid by the US customers.
        salesOrderObj.setSublistValue({
            sublistId: 'item',
            fieldId: 'amount',
            value: ItemInfo.Cost,
            line: line
        });
    }
    catch (e) {
        this.log.error({
            title: `addItem error: ${e.name}`,
            details: "An error occurred while adding an item to the sales order: " + e.message
        });
    }
}

Please use location. not inventorylocation

Thanks @Mark Oriend, I tried with location but it didn't work yet. I saw it is 'inventorylocation' to set the location for the line item in the documentation, specifically at https://system.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2022_1/script/record/salesorder.html, in the Sublists section. I guess it would be another problem but I don't know if this location depends on other fields I'm defining for the sales order.

inventory location and location are different fields with different purposes
