Plugin Update downloading current entity Reports cause time our error

Hi ,

I am troubleshooting with this issue from a week. i tried to post the issue through other sites i dint get any response.. please respond to my issue,

My task is to download the report and save to local file.

initially i created plugin on workorder entty for Update step. I have Report which  need to download and save the report by Form ID. In my report Prompt parameter is Entity ID. when am rendering the report though current Entity ID it gives time out exception.  if i hard code different form id through parameter value its rendering report bytes when i refer dynamical form id its giving channel time out exception.

I tried to trace report parameters value..its referring to right values but its throwing timeout exception..any one know the reason to time out  for current form id.. i tried to set the time out for 5 minuts..after 5 minutes its thworing the error by saying increase sendtimeout value.. :(

My error,

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: The request channel timed out while waiting for a reply after 00:01:00.

Since its giving timeout exception for cureent form id i started working with diffrent approach.

I created another plugin on CustomEntity On Create  download the report by reading workorder id from custom entity new field. 

My first plugin Work order Update creating new record through custom entity. when am calling through first plugin i could see its creating new record through custom enity , form loads for a while and throwing error 'Need to start a transaction before commit'. when workorderform realods newly created record deleted from custom entity. why..?

Error,

My code for 1st plug in,

 public void Execute(IServiceProvider serviceProvider)
        {
            IPluginExecutionContext context = (IPluginExecutionContext)
            serviceProvider.GetService(typeof(IPluginExecutionContext));
            Entity entity;
            ITracingService TracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
            // Check if the input parameters property bag contains a target
            // of the create operation and that target is of type Entity.
            if (context.InputParameters.Contains("Target") &&
            context.InputParameters["Target"] is Entity)
            {
                // Obtain the target business entity from the input parameters.
                entity = (Entity)context.InputParameters["Target"];
                // Verify that the entity represents a contact.
                if (entity.LogicalName != "new_workorder") { return; }
            }
            else
            {
                return;
            }
            try
            {
                TracingService.Trace("loading service factory");
                IOrganizationServiceFactory serviceFactory =
                    (IOrganizationServiceFactory)serviceProvider.GetService(
                typeof(IOrganizationServiceFactory));
                IOrganizationService service =
                serviceFactory.CreateOrganizationService(context.UserId);
                var id = entity.Id;
                var crmContext = new XrmServiceContext(service);               
                var contact1 = crmContext.New_WorkOrderSet.Where(w => w.New_WorkOrderId == id).First();
                new_esignature esign = new new_esignature();//custom entity
                if (!string.IsNullOrEmpty(contact1.new_inpersonsigninglinks) && !string.IsNullOrEmpty(contact1.new_EmailSigningLinks))
                {
                    TracingService.Trace("Creating new record  new_esignature");
                    esign.new_WorkOrderID = id.ToString();
                    crmContext.Create(esign);
                }
            }

second plugin,

  public void Execute(IServiceProvider serviceProvider)
        {
            IPluginExecutionContext context = (IPluginExecutionContext)
            serviceProvider.GetService(typeof(IPluginExecutionContext));
            Entity entity;
            ITracingService TracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
            // Check if the input parameters property bag contains a target
            // of the create operation and that target is of type Entity.
            if (context.InputParameters.Contains("Target") &&
            context.InputParameters["Target"] is Entity)
            {
                // Obtain the target business entity from the input parameters.
                entity = (Entity)context.InputParameters["Target"];
                // Verify that the entity represents a work order.
               // if (entity.LogicalName != "new_workorder") { return; }
                //new
                if (entity.LogicalName != "new_esignature") { return; }
            }
            else
            {
                return;
            }
            try
            {
                TracingService.Trace("loading service factory");
                IOrganizationServiceFactory serviceFactory =
                    (IOrganizationServiceFactory)serviceProvider.GetService(
                typeof(IOrganizationServiceFactory));
                TracingService.Trace("generating organization service from factory");
                IOrganizationService service =
                serviceFactory.CreateOrganizationService(context.UserId);
 var crmContext = new XrmServiceContext(service);        
                var contact1 = crmContext.new_esignatureSet.Where(w => w.new_esignatureId == esignid).First();
                string workorderid = contact1.new_WorkOrderID;
CreateReportPDF(sFilepath, workorderid.ToString(), id, ref TracingService);

Can anyone suggest me best approach??
