Below is a Plugin to create an Opportunity Clone [Cloning opportunity products as well].It uses early bound approach.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xrm.Sdk;
using Microsoft.Crm.Sdk.Messages;
using Entities = Pes.My.Configurations.Entities;
using System.ServiceModel;
using Pes.My.Configurations.Entities;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Xrm.Client;
namespace My.Crm.Plugins.Opportunity
{
public class PostUpdate : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
Entities.Opportunity oppRec;
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
// This plug-in was fired from the playback queue after the user selected to go online within Microsoft Dynamics CRM for Outlook.
if (context.IsExecutingOffline || context.Depth > 1)
return;
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
//Verify that the entity represents an Opportunity
if (((Entity)context.InputParameters["Target"]).LogicalName != Pes.My.Configurations.Entities.Opportunity.EntityLogicalName || context.MessageName != "Update")
return;
else
oppRec = ((Entity)context.InputParameters["Target"]).ToEntity<Pes.My.Configurations.Entities.Opportunity>();
}
else
{
return;
}
try
{
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
using (var MyContext = new MyContext(service))
{
if (oppRec.My_IsCloned == true)
{
if (context.Depth == 1)
{
Entity opportunity = null;
opportunity = service.Retrieve(Entities.Opportunity.EntityLogicalName, oppRec.Id, new ColumnSet(true));
Entity cloneopportunity = new Entity();
opportunity.Attributes.Remove("opportunityid");
opportunity.Id = Guid.NewGuid();
cloneopportunity = opportunity;
Guid ClonedOppId = service.Create(cloneopportunity);
List<Entities.OpportunityProduct> listoppproduct = MyContext.OpportunityProductSet
.Where(acp => acp.OpportunityId.Id == oppRec.Id).ToList<Entities.OpportunityProduct>();
foreach (OpportunityProduct objoppproduct in listoppproduct)
{
cloneOppProduct((Guid)objoppproduct.Id, ClonedOppId, service);
}
}
}
}
}
catch (InvalidPluginExecutionException)
{
throw;
}
catch (FaultException<OrganizationServiceFault> ex)
{
throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex);
}
}
private void cloneOppProduct(Guid guid, Guid Opp, IOrganizationService service)
{
Entity opportunityproduct = null;
opportunityproduct = service.Retrieve(Entities.OpportunityProduct.EntityLogicalName, guid, new ColumnSet(true));
Entity cloneopportunityproduct = new Entity();
opportunityproduct.Attributes.Remove("opportunityproductid");
opportunityproduct.Attributes.Remove("opportunityid");
opportunityproduct.Id = Guid.NewGuid();
opportunityproduct.Attributes["opportunityid"] = new EntityReference(Entities.Opportunity.EntityLogicalName, Opp);
cloneopportunityproduct = opportunityproduct;
service.Create(cloneopportunityproduct);
}
}
}
Note: I run this plugin from ribbon button "Clone Opportunity".Here I am setting Custom field "My_IsCloned " to true and saving the form using javaScript.And On post update it triggers this plugin.
Also you have to create an early bound class using CrmSvcUtil below is an example
CrmSvcUtil.exe /out:MyEntities.cs /url:https://Mydev1.api.crm.dynamics.com/XRMServices/2011/Organization.svc /username:name@My.com /password:pass123 /namespace:Pes.My.Configurations.Entities /serviceContextName:MyContext
Use the class generated i.e MyEntities [here] in your project and accomplish the same.
Hope this helps.
