Hello all,
I have two entities, Entity A and Entity B, joined by a N:1 relationship (B can have many As).
My plugin will fire upon creation of an Entity A, it needs to update an option set attribute in Entity B.
I'm having a lot of trouble implementing this, as simple as it seems. Since I'm using CRM online I cannot use Microsoft.Xrm.Client which would make this trivial. At the moment I'm trying to use retrieve to get the entity and update it. Here's my code:
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
//using Microsoft.Xrm.Client; NOT ALLOWED TO USE
namespace UpdateB
{
public class UpdateB : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
// Obtain the execution context from the service provider.
IPluginExecutionContext context = (IPluginExecutionContext)
serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory serveFactory = (IOrganizationServiceFactory)
serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = (IOrganizationService)serveFactory.CreateOrganizationService(context.UserId);
//get Entity A
Entity entity = (Entity)context.InputParameters["Target"];
//define it's guid ID
Guid guid = new Guid("2BC2B4EA-8715-E311-8E90-B4B52F67D682");
//define the attributes I want
ColumnSet cols = new ColumnSet(new string[] {"B_Attribute"})
//Retrieve entity B
Entity B = service.Retrieve("Entity_B", guid ,cols);
//update Entity B Attribute
citation.Attributes["B_Attribute"] = 100000002;
}
}
