通过按钮创建多个记录，但仅创建一个记录

Question

我试图在按下按钮时创建多个记录并将其显示在网格中。这些记录是在按下按钮时创建的，但是仅创建和显示一个记录。在测试中，我确定仅创建将由该过程创建的最终记录。按下按钮时，我没有收到任何错误，但仍然只得到一条记录。

    public PXSelect<TestDocument> Documents; //View of Grid

    protected void CreateDocument(ARInvoice invoice, ARPayment payment)
    {
        TestDocument testDoc = new TestDocument();
        //Creating TestDocument
        testDoc.CustomerID = invoice.CustomerID;
        testDoc.InvoiceID = invoice.RefNbr;
        testDoc.PaymentID = payment.RefNbr;
        testDoc.InvoiceTotal = invoice.CuryLineTotal;
        testDoc.PaymentTotal = payment.CuryLineTotal;
        testDoc.InvoiceDate = invoice.DocDate;
        testDoc.PaymentDate = payment.DocDate;
        Documents.Insert(testDoc);
        Persist();
    }

    public PXAction<FilterTable> Preview;

    [PXButton(CommitChanges = true)]
    [PXUIField(DisplayName = "Preview")]
    protected void preview()
    {
        foreach(PXResult<ARPayment> paymentResult in PXSelect<ARPayment, 
                Where<ARPayment.openDoc, Equal<True>>>.Select())
        {
                ARPayment payment = (ARPayment) paymentResult;

                //ARInvoices that are open and share CustomerID with the ARPayment
                foreach(PXResult<ARInvoice> invoiceResult in PXSelect<ARInvoice, Where<ARInvoice.customerID, 
                        Equal<Required<ARPayment.customerID>>, And<ARInvoice.openDoc,Equal<True>>>>
                        .Select(this, payment.CustomerID))
                {
                      ARInvoice invoice = (ARInvoice) invoiceResult;
                      CreateTransaction(invoice, payment);
                }
        }
    }

Answer 1

看来您的DAC缺少关键字段。

改为使用此属性定义TransactionID列：

[PXDBIdentity(IsKey = true)]
