总结
我为APInvoiceEntry 图表（AP301000 屏幕）创建了一个图表扩展，名为APInvoiceEntry_Extension。
我新建了一个名为APRegisterException的DB表，里面存储了SalesTax、Freight、Price和Qty错误的异常信息。APRegister和APRegisterException之间存在一对多的关系，表示账单可以有许多不同类型的异常。对于这些异常中的每一个，我创建了一个按钮和一个操作，以在我的扩展图中将异常添加到 DAC。
问题
我只能将 1 条新的 APRegisterExcetion 记录添加到 DAC。 DAC 不会针对多次单击按钮进行更新。以下每个操作都应创建一个新的 APRegisterException 记录，并将它们添加到我的图表中的 Exceptions DAC。
public PXAction<APInvoice> ApplyPriceException;
public PXAction<APInvoice> ApplyQtyException;
public PXAction<PX.Objects.AP.APInvoice> ApplyFreightException;
public PXAction<PX.Objects.AP.APInvoice> ApplySalesTaxException;
注意：动作正在执行，只是 DAC 没有 更新。
