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 }

View Code 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);
View Code
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。
