我们有一个要求，在“帐单类型”的“ AddPoReceipt”按钮的网格中仅显示“收据类型”，因为我试图覆盖如下所示的网格视图委托，但未能加载屏幕，也无法为此创建扩展图，请看看下面的代码也可以帮助我解决这个问题
预先感谢

When tried to add extension for this graph (AddPOReceiptExtension) got movenext error
When i wrote inheritance for this got method is not found error
答案 0 :(得分：3)
您需要扩展AddPOReceiptExtension图扩展名：
class MyExtension : PXGraphExtension<AddPOReceiptExtension, APInvoiceEntry>
该功能命名为Second-Level BLC Extension，并在此处记录：
https://help-2019r2.acumatica.com/Help?ScreenId=ShowWiki&pageid=c86fdae8-fef9-4490-aa57-3528d0fa172e
我精心制作了这个示例，以确保可以使用该方法扩展覆盖的AddPOReceipt：
using PX.Data;
using PX.Objects.AP;
using PX.Objects.CS;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using PX.Objects.PO.GraphExtensions.APInvoiceSmartPanel;
namespace PX.Objects.AP
{
public class AddPOReceiptExtension_Extension : PXGraphExtension<AddPOReceiptExtension, APInvoiceEntry>
{
public PXAction<APInvoice> addPOReceipt;
public PXAction<APInvoice> addPOReceipt2;
[PXUIField(DisplayName = PX.Objects.PO.Messages.AddPOReceipt, MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select, Visible = true, FieldClass = "DISTR")]
[PXLookupButton]
[APMigrationModeDependentActionRestriction(
restrictInMigrationMode: true,
restrictForRegularDocumentInMigrationMode: true,
restrictForUnreleasedMigratedDocumentInNormalMode: true)]
public virtual IEnumerable AddPOReceipt(PXAdapter adapter)
{
throw new PXException("Test Override");
}
[PXUIField(DisplayName = PX.Objects.PO.Messages.AddPOReceipt, MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select, Visible = false)]
[PXLookupButton]
[APMigrationModeDependentActionRestriction(
restrictInMigrationMode: true,
restrictForRegularDocumentInMigrationMode: true,
restrictForUnreleasedMigratedDocumentInNormalMode: true)]
public virtual IEnumerable AddPOReceipt2(PXAdapter adapter)
{
throw new PXException("Test Override 2");
}
}
}
