【问题描述】：
我认为我之前列出的一个问题运行良好，直到我注意到我需要的是 InventoryCD 而不是 InventoryID。在 KitAssembly 屏幕 (IN307000) 或 DAC 上找不到inventoryCD。因此，我创建了一个名为 UsrInventoryCD 的新 Usr 字段，并在填充 KitAssemblyID 字段时提取相同的 InventoryCD。这工作正常。接下来，我想获取此字段并将值从按钮传递到报告参数中。这是我目前所拥有的：
protected void INKitRegister_UsrInventoryCD_FieldSelecting(PXCache cache, PXFieldSelectingEventArgs e)
{
var item = (INKitRegister)e.Row;
if (item == null) return;
var invitem = (InventoryItem)PXSelect<InventoryItem,
Where<InventoryItem.inventoryID, Equal<Current<INKitRegister.kitInventoryID>>>>.Select(Base, item.InventoryID);
if (invitem != null)
{
e.ReturnValue = invitem.InventoryCD;
}
}

{
public override void Initialize()
{
Report.AddMenuAction(Report1);
Report.AddMenuAction(Report2);
Report.AddMenuAction(Report3);
Report.AddMenuAction(Report5);
Report.AddMenuAction(Report6);
Report.MenuAutoOpen = true;
}

{
INKitRegister item = Base.Document.Current;
var style = item.GetExtension<INKitRegisterExt>().UsrInventoryCD;
INKitRegister doc = Base.Document.Current;
if (doc != null)
{
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters["ItemNumber"] = style.ToString();
throw new PXReportRequiredException(parameters, "IN610002", "Report1");
}

它编译得很好，但是当我尝试单击已添加到屏幕上的报告按钮之一时出现此错误。

这是我问过的上一个问题是否与任何可能有用的信息有关：Acumatica - Add Reports dropdown to Kit Assembly Screen

我已经更改了上面的代码以适应我在一些文档中找到的更好的 DAC 扩展拉取。但是我仍然遇到同样的错误，我不知道我错过了什么，我知道这通常发生在它想要返回 null 或找不到它时。这不是从数据库本身中提取的，我的意思是如果保存被击中，它可以是，但它没有任何区别。无论哪种方式，我仍然会遇到相同的错误。
