Acumatica：如何在注销余额和贷方上添加额外过滤器 (AR505000)

Question

我需要在 Write Off Balances and Credits (AR505000) 上添加新过滤器。通常你必须复制 PXFilteredProcessingJoin 或 PXProcessingJoin 字段到扩展 class 和它附带的 IEnumerable 函数。但是在 Write Off Balances and Credits 页面中没有 IEnumerable。一种方法如何添加更多过滤器？

我正在考虑自己添加 IEnumerable：

public class ARCreateWriteOff_Extension : PXGraphExtension<ARCreateWriteOff>
{
    #region Event Handlers

    //THis is copied form the Graph
    [PXFilterable]
   // [PX.SM.PXViewDetailsButton(typeof(ARRegisterEx.refNbr), WindowMode = PXRedirectHelper.WindowMode.NewWindow)]
    public PXFilteredProcessingJoin<ARRegisterEx,  ARWriteOffFilter,
                                            InnerJoin<Customer,
                                                On<Customer.bAccountID, Equal<ARRegisterEx.customerID>,
                                                And<Customer.smallBalanceAllow, Equal<True>>>,
                                            LeftJoin<ARAdjust,
                                                On<ARAdjust.adjdDocType, Equal<ARRegisterEx.docType>,
                                                And<ARAdjust.adjdRefNbr, Equal<ARRegisterEx.refNbr>,

                                            LeftJoin<ARAdjust2,

要修改数据视图，您必须在图表扩展中重新定义数据视图class。在 BLC 扩展中重新定义的数据视图 完全替换了图形实例的视图集合中的基础数据视图 ，包括附加到基础图形中声明的数据视图的所有属性。您可以将同一组属性附加到数据视图或完全重新声明属性。数据视图必须具有完全相同的标识符（相同的名称），该标识符在 ASPX 页面的相应容器中引用。

或者，您可以通过在图形构造函数中添加新的 filters/joins 来更改现有数据视图（在扩展中，您可以通过覆盖图形扩展中的 Initialize 来实现）

public override void Initialize() 
{
  base.Initialize();
  this.Base.ARDocumentList.WhereNew< your new Where filter here >();
  //or WhereAnd< ... >(); to append contitions to existing one
  //you can also add this.Base.ARDocumentList.Join< _join a new table here >();
}
