Question

我在使用AX2012类时遇到问题（默认AX2012类和代码，未对其进行任何修改）：方法CustVendTransDetails中的calcCashDiscounts

以下查询给出了错误The select list for the INSERT statement contains fewer items than the insert list. The number of SELECT values must match the number of INSERT columns.：

if (TaxParameters::canApplyCashDiscOnInvoice_ES())
{
    insert_recordset tmpValue
        (CustVendTransRefRecId, AmountMST)
        select CustVendTransRefRecId
        from _custVendAccountStatementIntTmpProcessing

        exists join custVendTransLoc
        where
            custVendTransLoc.RecId == _custVendAccountStatementIntTmpProcessing.CustVendTransRefRecId

        exists join firstOnly subledgerVoucherGeneralJournalEntry
        where
            subledgerVoucherGeneralJournalEntry.Voucher == custVendTransLoc.Voucher &&
            subledgerVoucherGeneralJournalEntry.AccountingDate == custVendTransLoc.TransDate

        exists join generalJournalEntry
        where
            generalJournalEntry.RecId == subledgerVoucherGeneralJournalEntry.GeneralJournalEntry &&
            generalJournalEntry.Ledger == Ledger::current()

        join AccountingCurrencyAmount from generalJournalAccountEntry
        where
            generalJournalAccountEntry.GeneralJournalEntry == generalJournalEntry.RecId &&
            (generalJournalAccountEntry.PostingType == LedgerPostingType::CustCashDisc ||
            generalJournalAccountEntry.PostingType == LedgerPostingType::VendCashDisc);

    update_recordSet _custVendAccountStatementIntTmpProcessing setting
        UtilizedCashDisc = tmpValue.AmountMST,
        PossibleCashDisc = tmpValue.AmountMST
        join tmpValue
        where
            tmpValue.CustVendTransRefRecId == _custVendAccountStatementIntTmpProcessing.CustVendTransRefRecId;
}

我理解为什么，但我不知道如何解决这个问题。将exist join替换为普通join？

会有问题吗？

用exist join替换join确实解决了我的问题，但我不确定它会对数据产生什么影响？因为它只是选择1个字段？

您可以尝试切换联接顺序：

insert_recordset tmpValue (CustVendTransRefRecId, AmountMST)
    select CustVendTransRefRecId
    from _custVendAccountStatementIntTmpProcessing

    join AccountingCurrencyAmount from generalJournalAccountEntry // Moved up
    where generalJournalAccountEntry.PostingType == LedgerPostingType::CustCashDisc ||
          generalJournalAccountEntry.PostingType == LedgerPostingType::VendCashDisc

    exists join custVendTransLoc
    where
        custVendTransLoc.RecId == _custVendAccountStatementIntTmpProcessing.CustVendTransRefRecId

    exists join firstOnly subledgerVoucherGeneralJournalEntry
    where
        subledgerVoucherGeneralJournalEntry.Voucher == custVendTransLoc.Voucher &&
        subledgerVoucherGeneralJournalEntry.AccountingDate == custVendTransLoc.TransDate

    exists join generalJournalEntry
    where
        generalJournalEntry.RecId == subledgerVoucherGeneralJournalEntry.GeneralJournalEntry && &&
        generalJournalEntry.RecId == generalJournalAccountEntry.GeneralJournalEntry && // Moved from join
        generalJournalEntry.Ledger == Ledger::current();

Answer 2

使用加入替换现有联接不会解决您的问题。 Exist是一种基本连接到表的内部连接而不返回任何字段的方法。

查询应该从generalJournalAccountEntry返回来自_custVendAccountStatementIntTmpProcessing和AccountingCurrencyAmount的CustVendTransRefRecId，这正是插入所期望的。

我希望查询实际上没有返回任何内容。检查它使用的标准并检查数据。

用JOIN替换EXISTS JOIN
