getting error in calling create method of AIF web service in WCF web service application -- "Request Failed. See the Exception Log for details."

Hello,

I am getting error in integration of CRM and AX through custom web service.

First what i have done is i made a WCF web service in which i referenced my AX AIF web service.

And then i call that WCF web service on my CRM form on save. In this way i am going to integrate AX with CRM.

I am putting some code here...

            ax.SalesOrderServiceClient sc =new ax.SalesOrderServiceClient();
            sc.ClientCredentials.Windows.ClientCredential.UserName="crmusername";
            sc.ClientCredentials.Windows.ClientCredential.Password="crmpassword";

            sc.ClientCredentials.Windows.AllowedImpersonationLevel=System.Security.Principal.TokenImpersonationLevel.Impersonation;// Create an instance of the document class.
            ax.AxdSalesOrder salesOrder =new ax.AxdSalesOrder();// Create instances of the entities that are used in the service and// set the needed fields on those entities.
            ax.AxdEntity_SalesTable salesTable =new ax.AxdEntity_SalesTable();
            salesTable.CurrencyCode="INR";
            salesTable.CustAccount="C-00000001";
            salesTable.DeliveryDate=Convert.ToDateTime("11/28/2012");//salesTable.Payment = "100 %";
            salesTable.PurchOrderFormNum="PO";

            ax.AxdEntity_SalesLine salesLine =new ax.AxdEntity_SalesLine();
            salesLine.ItemId="ITEM00000015";
            salesLine.SalesQty=Convert.ToDecimal(10);
            salesLine.SalesUnit="NOS";
            ax.AxdEntity_InventDim inventDim =new ax.AxdEntity_InventDim();
            inventDim.configId ="--";
            inventDim.InventColorId="0";
            inventDim.InventSizeId="GENERAL";// Add the sub-entity instances to their parent entities as an array// of the sub-entity type.
            salesLine.InventDim=new ax.AxdEntity_InventDim[1]{ inventDim };
            salesTable.SalesLine=new ax.AxdEntity_SalesLine[1]{ salesLine };
            salesOrder.SalesTable=new ax.AxdEntity_SalesTable[1]{ salesTable };try{// Call the create method on the service passing in the document.
                ax.EntityKey[] returnedSalesOrderEntityKey = sc.create(salesOrder);// The create method returns an EntityKey which contains the ID of the sales order.
                ax.EntityKey returnedSalesOrder =(ax.EntityKey)returnedSalesOrderEntityKey.GetValue(0);returnstring.Format("The sales order created has a Sales ID of ",returnedSalesOrder.KeyData[0].Value);}catch(Exception e){returnstring.Format("Error Occurs :- {0}",e.StackTrace.ToString());}

I am getting error "Request Failed. See the Exception Log for details." at .create method call.

What can be done here.. Please help.
