使用圖形對象創建銷售訂單時出錯

Question

我試圖使用SOOrderEntry圖形對象從PO屏幕創建銷售訂單。我選擇使用從另一個堆棧溢出的情況下的技術分支，和我不斷收到以下錯誤：

我想不通爲什麼這個錯誤就要到了，因爲我設置客戶ID。下面的代碼：

public class POOrderEntryExt : PXGraphExtension<POOrderEntry> 
{ 
    public override void Initialize() 
    { 
     Base.action.AddMenuAction(CreateSO); 
    } 

    public PXAction<POOrder> CreateSO; 
    [PXUIField(DisplayName = "Create Sales Order", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)] 
    [PXButton] 
    protected virtual void createSO() 
    { 


     SOOrderEntry sograph = null; 
     SOOrder soorder = null; 
     SOLine soline = null; 

     //Let's get the current data from the screen we're in... 
     var poorder = (POOrder)Base.Document.Current; 
     PXResultset<POLine> res = PXSelect<POLine, Where<POLine.orderNbr, Equal<Required<POLine.orderNbr>>>>.Select(Base, poorder.OrderNbr); 

     using (PXLoginScope ls = new PXLoginScope("admin")) 
     { 

      //Create a new instance of the AP Bills screen graph.. 
      sograph = PXGraph.CreateInstance<SOOrderEntry>(); 

      //Get the branch... 
      var branch = (Branch)PXSelect<Branch, Where<Branch.branchCD, Equal<Required<Branch.branchCD>>>>.Select(Base, "WI-NVC VET"); 
      //soorder.BranchID = branch.BranchID; 

      //This handler is added per RD from another Stack Overflow case. It's necessary to select the Branch... 
      sograph.FieldDefaulting.AddHandler<SOOrder.branchID>((s, e) => 
      { 
       e.NewValue = branch.BranchID; 
       e.Cancel = true; 
      }); 


      soorder = new SOOrder(); 

      //The OrderType... 
      soorder.OrderType = SOOrderTypeConstants.SalesOrder; 
      sograph.Document.Insert(soorder); 

      soorder.OrderDate = (DateTime?)DateTime.Now; 
      soorder.RequestDate = (DateTime?)DateTime.Now; 



      //Get the customer id... 
      var bacct = (BAccountR)PXSelect<BAccountR, Where<BAccountR.acctCD, Equal<Required<BAccountR.acctCD>>>>.Select(Base, "NE-C003118"); 
      soorder.CustomerID = bacct.BAccountID; // (int?)5454; 

      sograph.Document.Update(soorder); 
      sograph.Actions.PressSave();

這是很進口PXCache插入或更新方法調用的結果總是分配給當地一些變量，以便進一步您從緩存中進行更改的對象，而不是一個傳統的記錄，與PXCache沒有任何共同之處。很多感謝 -

soorder = new SOOrder(); 
soorder.OrderType = SOOrderTypeConstants.SalesOrder; 
soorder = sograph.Document.Insert(soorder);
