jco3调用sap系统的rfc连接不上 请高手指点

帐号是没有问题的
错误代码：

有相关开发经验的人 希望指点指点。
我QQ 232691496

参考技术A 帐号权限有没有问题？RFC需要开通《Remote-Enabled Module》。 参考技术B EXEC ZRFCSD020 '0010000142','2010-10-25'

人首先应当遵从的，不是别人的意见，而是自己的良心。

C#如何通过RFC连接SAP系统

--定义SAPStart类：用于打开访问SAP的链接桥梁

public class SAPStart

{

//用于接收rfc配置     

public static RfcDestination rfcdest = null;

public static RfcRepository rfcrep = null;

//打开sap接口

public static void OpenSAP()

{

/ /如果rfcdest 、rfcrep 没有为空，则不需要再次打开链接的桥梁

if (rfcdest != null && rfcrep != null)

{

return;

}

try

{

//rfc配置 

string rfcname = "rfcname";

string rfcsystemid = "rfcsystemid";

string rfcappserverhost = "rfcappserverhost";

string rfcclient = "rfcclient";

string rfcuser = "rfcuser";

string rfcpassword = "rfcpassword";

string rfcsystemnumber = "rfcsystemnumber";

RfcConfigParameters rfc = new RfcConfigParameters();

rfc.Add(RfcConfigParameters.Name, rfcname);

----------Get 数据

public static void function_Get()
