    Do you have any info on event viewer?

    Did you try to run Page 39 from RTC?

    Was it running fine?

    Hi Mohana Yadav, Thank you for your valuable replay. I want to time to check bcos i am new in dynamics.my code is below:

    C# CodeSnippet below

    Gen_Ledger_Entry_Service    Service = new  Gen_Ledger_Entry_Service();

    Service.UseDefaultCredentials = true;

    Service.Url   =  “http://localhost:7047/DynamicsNAV/WS/CRONUS_International_Ltd Page/Gen_Ledger_Entry

    Gen_Ledger_Entry  GenEN=new Gen_Ledger_Entry();

    GenEN.Document_Type=0;

    This is d sample code for creating customer master.. you can find this sample code from navision help file and there are some others codes too...

    .//****

     Customer_Service service = new Customer_Service();

               service.UseDefaultCredentials = true;

               // Creates instance of customer.

               Customer cust = new Customer();

               cust.Name = "Customer Name";

               Msg("Pre Create");

               PrintCustomer(cust);

               // Inserts customer.

               service.Create(ref cust);

    //*****

    May i know , why you are inserting into  General Ledger Entry table...Its Strictly not advisable ......
