使用 webservices API 在 Acumatica ERP 系统的屏幕发票和备忘录中更新交货日期（自定义字段）

Question

我在屏幕发票和备忘录的标题中创建了新的附加字段，请参阅下面的屏幕截图。

下面是 DAC：

#region UsrDeliveryDate
public abstract class usrDeliveryDate : IBqlField{}
  [PXDBDate()]
  [PXUIField(DisplayName="Delivery Date", Visibility = PXUIVisibility.SelectorVisible)]

  public DateTime? UsrDeliveryDate
  {
      get;
      set;
  }

  #endregion

然后我使用下面的代码通过 webservices API 更新了这个交货日期：

try
        {
            sCon.getLoginInv(context);
            AR301000Content kon = context.AR301000GetSchema();
            var command2 = new Command[]
            {
                kon.InvoiceSummary.ReferenceNbr,
                kon.InvoiceSummary.Type,
                kon.InvoiceSummary.CustomerOrder,
                kon.InvoiceSummary.DeliveryDate
                //kon.InvoiceSummary.DueDate,
                //kon.InvoiceSummary.Customer
            };
            var filter = new Filter[]
            {
                new Filter()
                {
                    Field = new Field
                    {
                        FieldName = kon.InvoiceSummary.CustomerOrder.FieldName,
                        ObjectName = kon.InvoiceSummary.CustomerOrder.ObjectName
                    },
                    Value = "CNSE/17-III/00023"
                }
            };
            var result = context.AR301000Export(command2, filter, 0, false, true);
            foreach (var ax in result)
            {
                DeliveryDateClass delivDate = new DeliveryDateClass();
                delivDate.refNbr = ax[0].ToString().Trim();
                delivDate.type = ax[1].ToString().Trim();
                delivDate.custOrder = ax[2].ToString().Trim();
                delivDate.deliveryDate = ax[3].ToString().Trim();
                //delivDate.dueDate = ax[4].ToString().Trim();
                //delivDate.customerID = ax[5].ToString().Trim();

                kon.InvoiceSummary.Type.LinkedCommand = null;
                kon.InvoiceSummary.Type.Commit = false;
                var command = new Command[]
                {
                        new Value { Value = delivDate.type, LinkedCommand = kon.InvoiceSummary.Type},
                        new Value { Value = delivDate.refNbr, LinkedCommand = kon.InvoiceSummary.ReferenceNbr},

                        new Key
                        {
                            ObjectName = kon.InvoiceSummary.DeliveryDate.ObjectName,
                            FieldName = kon.InvoiceSummary.DeliveryDate.FieldName,
                            Value = "='" + delivDate.deliveryDate + "'"
                        },

                        new Value { Value = "4/20/2017", LinkedCommand = kon.InvoiceSummary.DeliveryDate },
                        kon.Actions.Save
                };
                context.AR301000Submit(command);
                sCon.getLogout(context, contextUntyped);
            }
            return "Update Success";
        }
        catch (Exception x)
        {
            MessageBox.Show(x.Message);
            return "FAILED";
        }
        finally
        {
            sCon.getLogout(context, contextUntyped);
        }

我会在下面更新此交易的交货日期。

但我有如下错误消息。

如果我在 Doc Type = "Invoice" 的交易中使用相同的代码，它可以工作，但对于 Doc Type = Credit Memo 的交易，它不起作用。

Answer 1

通过将 LinkedCommand 设置为 null 并将 Commit 设置为 falseType 字段的原因是什么/em>?

kon.InvoiceSummary.Type.LinkedCommand = null;
kon.InvoiceSummary.Type.Commit = false;

以下示例可以正常工作，无需对 Type 字段进行任何修改：

Screen context = new Screen();
context.CookieContainer = new System.Net.CookieContainer();
context.Url = "http://localhost/StackOverflow/Soap/AR301000.asmx";
context.Login(username, password);
try
{
    Content invoiceSchema = PX.Soap.Helper.GetSchema<Content>(context);
    var commands = new Command[]
    {
        new Value
        {
            LinkedCommand = invoiceSchema.InvoiceSummary.Type,
            Value = "Credit Memo"
        },
        new Value
        {
            LinkedCommand = invoiceSchema.InvoiceSummary.ReferenceNbr,
            Value = "AR004776"
        },
        new Value
        {
            LinkedCommand = invoiceSchema.InvoiceSummary.Description,
            Value = "Test"
        },
        invoiceSchema.Actions.Save
    };
    context.Submit(commands);
}
finally
{
    context.Logout();
}
