K2 BPM项目 基于COM组件调用SAP RFC 问题

问题前景：

　　环境：Win 2008 R2 64bit

　　最近项目中有支流程需求中需要在会计入账环节回写SAP的会计凭证。

　　SAP组给我们提供.NET基于COM组件调用SAP RFC的函数及参数，花费大量时间查阅资料终于知道怎么调用该函数：

 

SAPHelper.cs

  1 private string CompanyCode { get; set; }
  2         private string ProofDate { get; set; }
  3         private string PostDate { get; set; }
  4         private string OutSub { get; set; }
  5         private string InSub { get; set; }
  6         private string Amount { get; set; }
  7         private string Currency { get; set; }
  8         private string Text { get; set; }
  9         private string UserAccount { get; set; }
 10         private bool Flag { get; set; }
 11 
 12         public bool MoneyTransfer(string CompanyCode, string ProofDate, string PostDate, string OutSub, string InSub, string Amount, string Currency, string Text, string UserAccount)
 13         {
 14             this.CompanyCode = CompanyCode;
 15             this.ProofDate = ProofDate;
 16             this.PostDate = PostDate;
 17             this.OutSub = OutSub;
 18             this.InSub = InSub;
 19             this.Amount = Amount;
 20             this.Currency = Currency;
 21             this.Text = Text;
 22             this.UserAccount = UserAccount;
 23             Thread s = new Thread(new ThreadStart(Transfer));
 24             s.SetApartmentState(System.Threading.ApartmentState.STA);//Set the run mode 'STA'
 25             s.Start();//Start the thread
 26             s.Join(); //Wait until thread run OK.
 27             return Flag;
 28         }

调用：

1 SAPService service = new SAPService();
2                 this.ContinueProcessFlag = service.MoneyTransfer(txtPayCompanySAPCode.Text.Trim(), txtTransferDate.Text.Trim(), txtTransferDate.Text.Trim(), txtPaySAPAccountCode.Text, txtInComeSAPAccountCode.Text, txtPayAmountLow.Text, "CNY", txtTransferReason.Text, WebContext.Current.CurrentEmployee.UserAccount);

编译完后调试，OK。

本地调试OK。

然而发布到IIS上后问题出现了:

发布后调用调试IIS（怎么调试略），发现在if (conn.Logon(null, true))停留，无法登录。

经过研究与查阅大量资料后，基本确定问题是在与IIS在调用组件的权限问题上。根据http://wenku.it168.com/d_001035865.shtml 配置DCOM权限将“启动与激活”和“访问权限”改为自定义并加上EveryOne权限，将标识改为“交互式用户”，IIS应用程序池使用的是隶属于管理员组的域帐号，托管管道模式使用的是集成模式：

 

然而问题依旧，尝试过将应用程序池域帐号，IUSR组，IIS_WPG组加到“访问权限”和“启动和激活权限”，未果。

期待各位大虾门指点思路。
